Anne Frank is a sad, but true story about a teenag Essay Example For Students

Anne Frank is a sad, but true story about a teenag Essay e Jew living during WW II. Throughout the story Anne goes through a lot of troubles, trials and hardships. But also on the other hand she finds friendship, and she grows up. Throughout the whole story Anne is constantly fighting with her mother and her sister Margot. The thing about Anne, is that you could really look up to someone of her character and nature. She was always firm about what she believed in, and she was not afraid to stand up for it. Anne was also very grateful about every gift that she got in the Secret Annex. So in short she had a great outlook on life, even though she was in a small compact space with strange and annoying people. The story starts out at her thirteenth birthday. Then one day her older sister, Margot, gets the call from the German Police, the Gestapo. Her parents had been secretly sending things to the Secret Annex, without Anne and Margot knowing it, but they didnt know that it would come this soon. The Secret Annex was located over top of the building that Pim, Annes father owned. So the next day after the family packed up their stuff and went to the annex. Anne didnt even get to say good-bye to her friends. When they got to the annex, they heard through a good friend that there was another family that also needed a place to hide away from the Gestapo. This family was the VanDaans, so the Franks got ready for the VanDaans and awaited their arrival. The VanDaans also had a son, Peter, who was always quiet and always pretty much stayed to himself. Anne was very contrary, and she fought, and bickered with everyone in the house. Then as if they didnt already didnt have enough people in the annex, Meip found another person that needed some assistance and shelter. This man was Mr. Dussel, and his wife was already over in the states away from the Gestapo, but he didnt get so lucky. A few days before he had asked Meip about finding him a place to live, the Gestapo came and gave him his notice. So Meip told the Franks and the VanDaans, so that they could think about it and contemplate whether they had room for him. And they pondered over it and decided that they did infact have enough room for him. He would have to sleep with Anne in her room and they would share the room equally. But as time went on Mr. Dussel became stingy with his space and time, and he would not let Anne use the desk in her room for her own studies. So Pim decided to tell Mr. Dussel that he was a guest in their house, and when he came here they decided that they would share everything equally. And so with much persuasion Pim finally talked Dussel into letting Anne have some time to the desk by herself. So over time everyone got familiar with each other. The families of the Secret Annex didnt have very many means of entertainment, so they would entertain themselves. Peter and Anne would do little skits with each other dressing up as different people in the house. And most of the family members also tried out aerobics, but they got too sore too quick. So that was the end of that really quick! They would also tell stories and jokes to each other, they would read magazines that Miep brought them, they would read books, and they also would listen to the little radio in the office. .ud1af1fb103fddf78ef2fbe061a64fa27 , .ud1af1fb103fddf78ef2fbe061a64fa27 .postImageUrl , .ud1af1fb103fddf78ef2fbe061a64fa27 .centered-text-area { min-height: 80px; position: relative; } .ud1af1fb103fddf78ef2fbe061a64fa27 , .ud1af1fb103fddf78ef2fbe061a64fa27:hover , .ud1af1fb103fddf78ef2fbe061a64fa27:visited , .ud1af1fb103fddf78ef2fbe061a64fa27:active { border:0!important; } .ud1af1fb103fddf78ef2fbe061a64fa27 .clearfix:after { content: ""; display: table; clear: both; } .ud1af1fb103fddf78ef2fbe061a64fa27 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud1af1fb103fddf78ef2fbe061a64fa27:active , .ud1af1fb103fddf78ef2fbe061a64fa27:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud1af1fb103fddf78ef2fbe061a64fa27 .centered-text-area { width: 100%; position: relative ; } .ud1af1fb103fddf78ef2fbe061a64fa27 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud1af1fb103fddf78ef2fbe061a64fa27 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud1af1fb103fddf78ef2fbe061a64fa27 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud1af1fb103fddf78ef2fbe061a64fa27:hover .ctaButton { background-color: #34495E!important; } .ud1af1fb103fddf78ef2fbe061a64fa27 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud1af1fb103fddf78ef2fbe061a64fa27 .ud1af1fb103fddf78ef2fbe061a64fa27-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud1af1fb103fddf78ef2fbe061a64fa27:after { content: ""; display: block; clear: both; } READ: Exemplification Essay This radio became a very important part of their life, and they didnt even realize it.

Animal Farm and the Russian Revolution of 1917 Essays

Animal Farm and the Russian Revolution of 1917 Essays Animal Farm and the Russian Revolution of 1917 Paper Animal Farm and the Russian Revolution of 1917 Paper Essay Topic: Animal Farm Animal Farm Russian Revolution George Orwell’s book Animal Farm (published in1943) is a children’s story, but when closely examined, it proves to be an allegory to the Russian Revolution. The events in the book are very closely related to the actual events from The Russian Revolution. Also, the animals (main-characters) are historically referring to the Communist leaders such as Leon Trotsky, Joseph Stalin, Karl Marx, and others. The book starts out with Old Major speaking to his fellow animals (representing the people during the Revolution). Old Major represents either V. I. Lenin or Karl Marx. Either way, he is representing the father of Communism. His speech urges the animals (â€Å"workers of the world†) to unite against their economic oppressors (humans in the book, Hitler in the Revolution). Old Major dies before he can see the way his followers carried on, as Lenin also died before he was able to witness final results of the Revolution. After Old Major (Lenin) dies, the three pigs Napoleon (Joseph Stalin), Snowball (Leon Trotsky), and Squealer (Stalin’s propagandist) develop the concept â€Å"Animalism†. This concept was really a fictional way of explaining Karl Marx’s Communist vision. This is when the animals decide to rebel and take over Manor Farm, giving it the new name Animal Farm. Every animal worked hard on the farm, and the revolt started as a success, as the Russian Revolution did. Previously, the animals had lead hard lives. Under Jones’ (Nicholas’) reign, the lives of millions of Russians got worse. The farm is overtaken from Jones, representing when Nicholas’ own generals withdrew their support of him. Nicholas left his throne hoping to avoid a civil war, but the war arrived anyway (in the form of the Bolshevik Revolution). Nicholas, like Jones, was removed from his place of rule. He died shortly after. Trotsky’s ideas were reflected when Snowball made plans to build the windmill. He thought it was the best way to put Old Major’s(Lenin/Marx) theories into practice. Trotsky’s army is also shown as the army of animals Snowball directs to get rebel against Jones. As Trotsky was exiled and killed by Stalin’s agents, Snowball was chased off the farm by Napoleon. Stalin gained powerful dictatorship; Napoleon gained powerful dictatorship. Power was valued, and cruel acts of terror and brutality broke out. Napoleon’s dogs are like Stalin’s secret police that he used to eliminate to get in complete control. Using Squealer (propaganda), Napoleon gains control and is able to affect the animal’s lives. The plan to build the windmill after all reflects Stalin’s Five Year Plan for growing the worlds industry etc. When Napoleon digs up Old Major’s skull, it represents how Stalin ordered Lenin’s body to be placed in the shrine-like tomb for Lenin. Napoleon’s starting of the Order of the Green Banner is Stalin’s starting of the Order of Lenin. The Battle of the Cowshed represents the Civil War that occurred after the Revolution. Adolf Hitler is represented by Frederick who formed an allegiance with Stalin(Napoleon), but somehow ended up fighting Stalin’s army later on. Frederick’s fake money revealed that he hadn’t been a true ally to Napoleon. Stalin’s purge is shown by Napoleon’s executions of the animals that confessed. Stalin conducted to rid himself of any possible threat, as Napoleon did in the book. As the hens began to rebel against Napoleon, so did the sailors at the Kronshdadt military base rebel against Communist rule†¦ the attempts to rebel failed. The Battle of the Windmill later on in the book reflects the U. S. S. R. ’s involvement in World War II (but more specifically the Battle of Stalingrad-1943). Stalin’s forces defeated Hitler’s (as Napoleon’s forces defeated Frederick). At the end of the book, the card game represents the Tehran Conference, where Stalin, Winston Churchill, and Franklin Roosevelt met to discuss the ways to make a lasting peace after the war. Orwell mocks that peace in the book by having Napoleon and Pilkington flatter each other and then betray their natures by cheating in the card game. Animal Farm was written to make fun of Stalins corrupt rule in Russia. It was written based on The Russian Revolution, but it definitely shows how any Revolution can go wrong and get out of hand, like in the book. MAIN THEME: â€Å"The theory of a country in which everyone is equal, free and happy is but an illusion, a deception of reality, which is, that ‘power corrupts and absolute power corrupts absolutely’. That once tainted with the feeling of power, most will stoop to any level, and do whatever the cost to maintain that power. †

Aust. Poverty and Education essays

Aust. Poverty and Education essays Many serious issues face this country today, and two of the most important of these issues are poverty and the provision of health care and education, both in our country and worldwide. Australia is assisting in the fight against poverty in a large way, both in Australia, and on a global scale. Australias has three main objectives in health care and aid. The three objectives are to improve the basic health of those in need, to improve the quality of health service delivery in developing countries and to address the health effects of natural disasters and emergencies. In 2000-2001, Australia will provide over $170 million of assistance to developing countries in many areas around the world. It is obvious that the large majority of human death in the developing world is poverty-related. Australia has been trying to improve health standards and access to basic health services for the less fortunate groups of citizens. Developing countries are generally the world's poorer countries, which are still in the process of developing their human, physical, and technological resources in order to improve the standard of living of their people. Developed countries are the world's richer countries and are in a position to offer assistance to developing countries. Australia is obviously developed, therefore is involved in many foreign aid programs in about 130 countries. Some forms of aid that Australia provides are: Project aid for curing and vaccinating harmful diseases like malaria, improving water supplies etc. , education and training programs, technological aid in the form of equipment and expert knowledge provided for agriculture, industry and other activities as well as food aid, such as emergency food aid given if a crisis is at hand. Often emergency relief, such as food, medicines, shelter materials and clothing are donated to people affected by natural or human disasters, or war, and often distributed by non-governm...

Improving macro-organizational communication in organization Essay

Improving macro-organizational communication in organization - Essay Example But, in an organization, these workers will normally be apportioned or â€Å"structurized† into departments for better arrangement and streamlining of work. These different departments can only boost an organization by working in unison, and thereby actualizing the opportunities on offer, so they could reach their targets and the estimated profits. So, ‘working in unison’ is the key, and the ‘key’ which opens up the minds of the workers working in the department, and aid ‘unison’, is communication. That is, communication between organization’s different departments or etc will only help the workers to work as a team and help them in coordinating and concluding the given work successfully. So, this paper will analyze how to improve the macro communication in an organization using Electronics, with Harley Davidson as a guide. Providing a perfect and barrier environment to the workers will develop communication in an effective manner. For that the management should initiate new methods and if those methods are based on technology, it will surely provide optimum results. With many organizations diversifying physically with units and sister concerns being established at different places, there has to be seamless communication for the effective functioning of the organization. Same way, if an organization also concentrates on the sale or supply side of its products and services, communication need to be established between the manufacturing unit and the sale or supply side. In these situations, where physical distances could be the barrier, technology and the technological products will only break that barrier and will help to maintain the communications, thereby benefiting the organization in many ways. Among the many technological products, the electronic ones could be bring in immense benefits and we can see this by analyzing how Harley Davison used the electronic equipment of RFID to maintain

The Local Colors Writing of Kate Chopin's The Awakening Essay

The Local Colors Writing of Kate Chopin's The Awakening - Essay Example In the end, despite her developments into selfhood, the only escape from her biological destiny as a woman in society, possessed, sexual, and ruled, is death. Local Color writers were an offshoot of the Realistic movement. They sought to preserve a distinct way of life threatened by industrialization, immigration, the after effects of the War, and the changes in society. Their writing concentrated upon rendering a convincing portrait of a particular region and delving below the surface picture to reveal some universal aspect. What this novel wants to convey is that immigration is not as sweet as most people think. People are more interested and amazed on how well immigrating families are doing by the clothes they wear, the cars they drive, the way they speak fluent English and etc. Those are all superficial because behind the achievements are hardships of which not everyone has a clear understanding of. Difficulties are always abundant and it takes it toll on every member of the family. There is never a way in which immigration can always be smooth sailing. Immigrants tend to be victims of abuse by people around them who knows they are vulnerable. he relationship between men and women and the economic aspects that go along with that issue are also realistic. Edna is "owned" at various points in the novel by her father, husband, Arobin, and Robert.

PED 131 Essay Example | Topics and Well Written Essays - 500 words

PED 131 - Essay Example In the paper I got the second question wrong. The question was -When the command Cease Fire is given other than the range office. My answer to this was (b) Stop shooting immediately, lay the gun down on the bench and await further instructions. The reason I chose this answer was because when someone gives the command to cease fire it could be because there is some hazardous situation. Thus the best way to avoid any danger would be to stop firing and lay the gun down. But the correct answer is (d) since the correct thing to do would be to stop firing, point the gun in a safe direction and call or wait for the range officer to give further orders and if needed clarify as to why someone else gave the order. My answer to question 3 was because I felt that after notifying the range officer the best thing to do would be to open the action and remove the cartridge since in order to continue firing I would have to remove the faulty cartridge. But the correct answer to this is (d) since it is the range officer who is responsible to over see the removal of the cartridge. My answer to question 5 was (b) since in all the guns I have seen till date the safety switch has always been on the side and no where else.

Single Phase To Three Phase Converter Engineering Essay

Single Phase To Three Phase Converter Engineering Essay Several solutions have been proposed where the objective is to reduce harmonic distortions in a generating system. It is now the renewable power utilization that is growing more, thus a small scale Wind Energy Conversion System is concentrated which needs harmonic reduction. The wind energy unit that we are planning to install is single phase so we go for a single phase to three phase ac-dc-ac converter designing to reduce harmonics. Parallel converters have been used to improve the power capability, reliability, efficiency, and redundancy. Usually the operation of converters in parallel requires a transformer for isolation. Here a single-phase to three-phase drive system composed of two parallel single-phase rectifiers and a three-phase inverter is proposed. Compared to the conventional topology, the proposed system permits: to reduce the rectifier switch currents; the total harmonic distortion (THD) of the grid current with same switching frequency or the switching frequency with s ame THD of the grid current; and to increase the fault tolerance characteristics. Also the loss of the proposed system is lower. The aforementioned benefits justify the initial investment of the proposed system, due to the increase of number of switches. Index Terms- Converters, IGBT, MOSFET, Renewable Energy, Single Phase to Three Phase, Wind Energy. Introduction The paper deals with the enhancement of the usage of renewable energy and improvement of its utility. Wind energy is one of the most promising alternative energy technologies of the future. Throughout recent years, the amount of energy produced by wind-driven turbines has increased exponentially due to significant breakthroughs in turbine technologies, making wind power economically compatible with conventional sources of energy. One of the limitations of wind energy is Harmonic distortion that hinders the utility of the wind generation. Harmonics is referred as the disturbance or the deterioration of the purity of current or voltage after undergoing several changes or transformations. Since power quality is very important it is mandatory to discover methods to reduce harmonics and retain purity. As corrective action is always expensive and unpopular solution more thought and investment are devoted at the design stage on the basis that prevention is better than cure. The sources of harmonics can be divided into 3 categories: Large numbers of distributed non-linear components of small rating. Large and continuously randomly varying non-linear loads. Large static power converters and transmission system level power electronics devices. Harmonics Reduction Technique In general there are many techniques to reduce harmonics like usage of harmonic filters [13] PWM technique [4], [5], [13] Filter is a device that is designed to suppress harmonic current and voltages from being injected into the power system since these causes damaging effects to the devices being used in the system. The harmful and damaging effects of harmonic distortion can be avoided by the usage of filters. There can be two types of filters that are used in order to reduce the harmonics distortion i.e. the active filters and the passive filters. Active harmonic filters are electronic devices that eliminate the undesirable harmonics on the network by inserting negative harmonics into the network. The active filters are normally available for low voltage networks. In order to control power and reactive power, it is essential to control the magnitude and phase angle of the injected voltage by the converter [1], [4], [5], [7]. At the same time, it is desirable to regulate the DC bus voltage. Another requirement is to minimize the injection of the lower order harmonics by the converter. The pulse width modulation (PWM) is utilized to achieve the following objectives: To control the output AC voltage for a constant DC voltage. To minimize the harmonics subject to the constraints on the switching losses, generation of noise etc. Circuit Design The project deals with a converter design as an attempt to reduce harmonic distortions in wind energy conversion system. We design a converter circuit for a single phase three phase conversion with two single phase rectifiers connected in parallel and a three phase inverter. The experiment is simulated using MATLAB Simulink software and the results are compared for the effectiveness of the converter circuit [9]. Also the selection of switch for the converter is very essential thus we compare two different switches- MOSFET and IGBT and analyze its characteristics for the suitability and effectiveness. Process of Switch Selection The below table shows the comparison of different parameters considered in the course of selection of switch for the converter thereby helping us to justify our selection. The Table below shows the comparison between different possible switches that are used in converters. We can see the characteristics and parameters based on which the switches are selected. TABLE I. SELECTION OF SWITCH FOR THE CONVERTER CIRCUIT Device Comparison area diode rectifier Thyristor [SCR] GTO IGBT MOSFET Inverter switch X X AC-DC conversion X X X X X Inverter types Current source X X Voltage source X X X Efficiency High High Low High High Gate control signal NA current current voltage voltage Gate current NA < 2 Amps 400-1000 Amps 0.1 Amps < 0.01 Amp Voltage rating High High High To 1200 Volts 4000 volts Current rating 6000 Amps 5500 Amps 1000 Amps 1000 Amps 600 Amps Switching losses NA Medium High Low Low Switching speed NA Low Low Very high Very High From the comparison it is evident that MOSFET, IGBT are the two most suitable switches for the Inverter section of converter as MOSFET and IGBT showed good efficiency, voltage and current ratings. Also the switching speed and switching losses are satisfactory. And it doesnt need a special switching angle control mechanism. Thus the MOSFET, IGBT rectifier/inverter system is the proposed converter for the small scale wind energy conversion system. Also comparison between MSOFET and IGBT operation in Single phase Three phase conversion as well as Three phase Three phase conversion is done. Technology used for switching The maximum achievable efficiency of any practical system is 0.93. However due to design considerations and operational constraints, the percentage drastically reduces to a maximum of 0.5, in the case of a wind energy system. The aim of this project is to improve the normal operating mean efficiency of 0.29. Various techniques have been instrumental in reducing the overall losses in the system, and also particular interest is streamlined in the domain of reduction of harmonics in the system. A lot of techniques by which, losses, and particularly, harmonics can be reduced have been figured out by analyzing various IEEE projects. Apart from circuit element modifications, design modifications have also been analyzed. The Circuit Design Here as per the circuit diagram we can see 14 switches totally i.e. 4 for each single phase rectifiers and 6 for the three phase inverter. Now when the single phase supply is given to the system the rectifiers convert the AC single phase supply to DC supply then it is fed to the inverter for further conversion into a three phase AC supply. Here as we can see the rectifiers are connected in parallel to each other, as we know the working of the rectifier. The converter can either use MOSFET as a switch or IGBT as a switch. FIGURE 1. CIRCUIT DESING FOR SINGLE PHASE_ THREE PHSE CONVERTER Here as per the circuit diagram we can see 14 switches totally i.e. 4 for each single phase rectifiers and 6 for the three phase inverter. Now when the single phase supply is given to the system the rectifiers convert the AC single phase supply to DC supply then it is fed to the inverter for further conversion into a three phase AC supply. Here as we can see the rectifiers are connected in parallel to each other, as we know the working of the rectifier. The converter can either use MOSFET as a switch or IGBT as a switch. Rectifier is a device that converts AC to DC signal. In a single phase controlled rectifier there are 4 switching devices two in each leg. Two switches at a time namely alternate switches of the legs are on at a time. Thereby converting the AC signal into DC signal. Then it is fed to the inverter which has 6 switching devices two per leg, thus a 3 phase inverter has 3 legs with 2 switches per leg. The working mechanism is almost similar to the rectifiers. Simulation using MATLAB/Simulink MOSFET Based Converter Simulation The MATLAB simulation model clearly depicts the no of switches used, also the parameters involved in the analysis of the circuit. Simulation results help us clearly conclude the difference in the performance based analysis of MOSFET and IGBT converters. C:Documents and SettingsBIRDDesktopchithra simulationmosfet singlemosfet single.bmp FIGURE.2 MOSFET based Single phase three phase converter using MATLAB Simulation MATLABÂ  is a high-level language and interactive environment for numerical computation, visualization, and programming. Using MATLAB, you can analyze data, develop algorithms, and create models and applications. The language, tools, and built-in math functions enable you to explore multiple approaches and reach a solution faster than with spreadsheets or traditional programming languages, such as C/C++ or Java. Here we simulated converter circuit with MOSFET switches and IGBT switches and compared the difference in the capacity of reducing harmonics. FIGURE.3 RECTIFIER OUTPUT FOR MOSFET BASED SINGLE PHASE THREE PHASE CONVERTER USING MATLAB SIMULATION. This graph represents the rectifier output. The voltage amplitude is 310V i.e. the harmonics in the voltage causes spikes which reaches this value, where as the original voltage is around 230V. The graph is plotted for a time period of 20 milliseconds. The positive half wave is rectified better than the negative half wave. We can clearly see the spike occurrence in the positive half wave due to harmonics. . FIGURE. 4 FINAL OUTPUT OF THE MOSFET BASED CONVERTER SYSTEM USING MATLAB SIMULATION The output is around 220V with reduced harmonics. The inverter output by itself has reduced harmonics distortion found in the rectifier output. The spikes that were found in the rectifier are not present in the inverter output waveform. From this its evident that the single phase to three phase voltage converter design helps in reducing the harmonics. The MOSFET switch used is a voltage controlled device and has a high switching frequency that enhances the rectification as well as inversion of the generated voltage. The single phase to three phase configuration is helpful in reducing the harmonics is hence proved from the graphs above.

In this graph the magnitude of output is around 220V which means the input is completely rectified. The occurrence of spike is at the junction of two half waves. Thus the completeness of the half waves is affected by the harmonic distortions in the case of IGBT based converter. C:Documents and SettingsBIRDLocal SettingsTemporary Internet FilesContent.Word220op.bmp FIGURE.VII FINAL OUTPUT WAVEFORM OF THE SYSTEM WITH 220V SUPPLY The output graph shows the reduction in harmonics to some extent the magnitude of harmonics is reduced and is evident in the output graph. ANALYSIS OF HAMONIC REDUCTION WITH VARIATION OF INPUT INDUCTANCE Initially we analyzed the system effectiveness for various input voltages like 230V, 220V, 200V etc., where we found a prominent result only for 220V input supply. Now that changing in voltage is not producing enough difference thus we try to change the input inductance and realize the effectiveness of the MOSFET and IGBT based conversion systems. FIGURE. 8 GRAPHICAL REPRESENTATION OF VARIATION OF HARMONICS WITH VARIATION OF INDUCTANCE IN A MOSFET BASED SINGLE PHASE THREE PHASE CONVERTER In the single phase to three phase conversion topology of converter using MOSFET, the inductors L2 and L4 (corresponding to the negative cycle of supply) are varied from 0.1 mH to 0.4 mH under a varying operating voltages between 220 V and 230 V. The results that are thus obtained are represented in the graph. For operating voltage 220 V, the output voltage peak varies between 214.4 V and 206.1 V corresponding to the change in input inductance values between 0.1 mH and 0.4 mH. Similarly, for operating voltage 230 V, the variation in peak voltage is between 224.2 V and 215.4 V for the same change in input inductance. FIGURE.9 GRAPHICAL REPRESENTATION OF VARIATION OF HARMONICS WITH INDUCTANCE IN AN IGBT BASED SINGLE PHASE THREE PHASE CONVERTER. In the single phase to three phase conversion topology of converter using IGBT, the inductors L2 and L4 (corresponding to the negative cycle of supply) are varied from 0.1 mH to 0.2 mH under a varying operating voltages between 220 V and 230 V. The results that are thus obtained are represented in the graph. For operating voltage 220 V, the output voltage peak varies between 219.4 V and 216.5 V corresponding to the change in input inductance values between 0.1 mH and 0.2 mH. Similarly, for operating voltage 230 V, the variation in peak voltage is between 229.8 V and 226.3 V for the same change in input inductance. In the above graphs we see the variation of harmonics with the variation of input inductance thus choosing the input inductance wisely can affect the harmonics reduction process. CONCLUSION As per the above result and discussion we saw the variation of harmonics with variation of voltage magnitude and input inductance accordingly, with the result we observe that single phase three phase MOSFET based converter reduces spikes to a great extent without any loss in the voltage magnitude when the input inductance is of 0.1mH each. But when the inductance is changed to L1, L3= 0.1mH and L2, L4=0.4mH the output consists of negative peaks without loss in voltage magnitude. Coming to IGBT based converter, the single phase three phase converter has low harmonics in the rectifier as well as the inverter outputs when the inductance in L1, L3=0.1mH and L2, L4=0.2mH.when the inductance is changed to 0.1mH all the rectifier output has little heavy spike at the junction of the half waves which are reduced without voltage loss.
