Comparative study of harmonics and total harmonic distortion of five-phase inverter drive with five-phase multilevel inverter drive using simulink/MATLAB

Abstract

Harmonics are created in the output of the Inverters due to nonlinear loads. These harmonics not only causes excessive heat in the devices or appliances used in the daily life of human being, but also reduces the life period of the appliances. This reduction of harmonics in such system has become great concern for the engineers. Multilevel inverter technology has proved to give improved harmonic performance. This paper presents simulation of harmonic analysis in five-phase two-level inverter and five-phase multilevel (three level). It has been found that the total harmonic distortion (THD) is less in case of five-phase three-level inverter.
