Comparative analysis of SVPWM and SPWM techniques for multilevel inverter

摘要

The aim of this paper is to analyze the comparative relationship between Space-Vector Pulse Width Modulation (SVPWM) and Sinusoidal Pulse Width Modulation (SPWM) for three phase multilevel inverters. Detailed comparative analysis of Total Harmonic Distortion (THD) for both modulation strategies analyzed. The converter technologies are receiving increased attention due to high power applications. This increased attention is probably due to the fact that the output waveforms are much improved over those of the three-phase carrier based sinusoidal pulse width modulation (SPWM).
