An Extensive Review of different PWM Techniques

Abstract

In Alternating Current Power, the quantity of sinusoidal waveform is not matters.The important is quality of sine waveform than quantity so to improve the quality of waveform,the reduction in harmonic content is necessary.For this achievement, different PWM techniques is used.This paper includes four basic PWM techniques single PWM,multiple PWM ,sinusoidal PWM and Hysteresis PWM.
