Abstract

This paper deals with the comparison of nine level and eleven level neutral point clamped inverter .A conventional voltage source inverter (VSI) is modelled and simulated using matlab.FFT Analysis is done to study the reduction in Total Harmonic distortion (THD).Multilevel converter is used to increase high level output voltage magnitude ,reducing the output voltage and current harmonic content make output voltage closer to sinusoidal wave the switching frequency.
