Abstract

Power electronics deals with variety of converters that are used at power level rather than the signal level. The commonly used type of converters are DC to DC, DC to AC, AC to AC and Cycloconverters, these converter finds industrial applications. Pulse width modulation (PWM) is one of the techniques used in power electronic converters. This is the most preferred method since PWM offers many advantages. In this dissertation, the applications of PWM techniques on different types of power electronic converters are studied. The simulation is carried out using SIMULINK and MULTISIM. In the first part of this paper, the generations of PWM signal using different methods are explained. Using Multisim, different PWM generating circuits are analyzed and the results are discussed. The application of PWM converters like on dc to dc buck boost Converter, DC to DC mono-polar inverter, DC to AC bipolar inverter, half bridge inverter, full bridge inverter, cycloconverter, AC - DC -AC converter are simulated using simulink. These are explained and results are discussed.Lastly in this paper explains about simulation of power electronic converters on ac to ac converter is used for analysis of PWM, here ac voltage regulator operating on both uniform pulse width modulation and sinusoidal pulse width modulation principle under loading conditions Mat lab results of both PWM is verified. In this dissertation One more program is simulate i.e. for dc to ac converter is used and generate the PWM waveform. The mat lab values for different carrier frequency verified and analysis the result.
