Hardware Implementation of Single Phase PWM Rectifier

Abstract

This paper investigates the method of obtaining unity power factor operation in pwm rectifier. A brief description of the switching sequence adapted for obtaining upf operation is explained. In this work a MATLAB simulation was performed to analyse the working of rectifier for a resistive load. The waveforms so obtained are analysed for various harmonics injected by them. Later a hardware prototype was made to validate the results of simulation. A resistive load of 200W was taken for the experimental setup. The input current and voltage waveforms obtained in the hardware set up are also in phase and validates the simulation results.
