چکیده
In thispaper comparative performance analysis of MOSFET based& IGBT based single phase inverter has been evaluted. The paper compares overall THD of output voltage of thesetwoproposedinverters. Heresinusiodal PWM scheme has been usedwhich compares a sinusoidalreference voltage with a carrier basedmodulating signal to generategating pulse for inverter circuit. Power quality of inverter output voltage has a great importance now a dayswhichdepends on overall THD.This paperdescribes how THD of inverter output voltage canbecontrolled by varyingfrequency of carrier signal frequency.
