Abstract

This study presents a modified single phase cascaded 15 level inverter with reduced switch count that operates in asymmetric mode. The proposed multilevel inverter produce DC voltage levels similar to other topologies with less number of semiconductor switches. This study also presents various modulating techniques include sinusoidal pulse width modulation, advance modulating technique. i.e., Trapezoidal reference with triangular carrier waves. Different performance measures like THD, VRMS and CF have also been evaluated by simulation. The simulation of proposed circuit is carried out using MATLAB/SIMULINK and the result for the same are presented in this study.

Keywords:

Crest factor, form factor, THD, unipolar carrier overlapping, unipolar phase disposition,
