Matlab Simulink Model of Sinusoidal PWM For Three-Phase Voltage Source Inverter

This paper concentrates on modeling and simulation of single phase inverter as a frequency changer modulated by sinusoidal Pulse Width Modulation PWM technique. An inverter is a circuit that converts DC sources to AC sources. To judge the quality of voltage produced by a PWM inverter, a detailed harmonic analysis of the voltage waveform is done. Pulse width modulated PWM inverters are among the most used power-electronic circuits in practical applications. These inverters are capable of producing ac voltages of variable magnitude as well as variable frequency with less harmonic distortion. The model is executed utilizing MATLAB Simulink software with the SimPower System Block Set using PC simulation. MATLAB Simulink is a successful instrument to examine a PWM inverter. Major reasons for using MATLAB are Faster reaction, accessibility of different simulation devices and the nonappearance of joining issues. In this paper, Insulated Gate Bipolar Transistor IGBT is used as switching power device. IGBT is ideal since it high switching speed and also high input impedance. Finally a MATLAB SIMULINK model for the SPWM is presented. Various simulation results are also included.
