Abstract

A selective harmonics elimination (SHE) method for Cascaded H-Bridge (CHB) multilevel inverter (MLI) is proposed in this paper. The proposed modulation scheme is a low switching frequency modulation scheme and it is derived from the nearest level modulation scheme. The proposed modulation scheme reduces the total harmonic distortion (THD) at the ac output of the inverter. The SHE follows an algorithm presented in the paper in order to arrive at a set of switching angles for MLI which offers reduced THD. The Simulation is carried out using MATLAB / Simulink 2015b software and the results are presented which validates the simulation results. Results show that the lower order harmonics are eliminated in the THD content with the use of proposed modulation scheme. As a result of the improved THD content, improvement in the other inverter parameters such as rms voltage, rms current and output power is also observed.
