Abstract

Renewable energy has made quite a mark in the world’s growing energy demand. This form of energy is proven to be economical as well as environmental-friendly. This calls for the need of DC to AC power conversion, which is achieved by means of an inverter. Greater harmonic distortion, higher switching losses and poor power quality waveform were the main setbacks of former inverters, this created a path for the advent of multilevel inverters. In this paper, a 7-level asymmetric CHB-MLI has been modelled via MATLAB/SIMULINK software. In order to further reduce the THD and control the output, multicarrier PWM technique of phase opposition disposition has been implemented. THD for the proposed scheme has been calculated to be 16.24%. THD analysis has been carried out, using FFT analysis tool of MATLAB/SIMULINK. 7-level voltage output has been displayed. A comparison of various parameters of different topologies with the proposed topology has been accomplished.
