Performance of a novel multi level inverter based on modulation techniques

Abstract

The aim of the paper is to introduce a symmetrical multilevel inverter (MLI) with a basic module. This novel MLI have a group of components containing H-bridge which results in reduced device count thereby lowering the losses in the devices when related with other regular and recent MLI. Various control methods are employed to the novel inverter and a comparative study is made. FFT analysis is used and harmonic spectrum is analyzed. The evaluation and functioning of the novel inverter is verified through simulation using MATLAB/Simulink software.
