Study of harmonic performance in conventional multilevel inverters: Comparative analysis of modulation techniques

Abstract

This review paper evaluates the integration of Space Vector Modulation (SVM) with basic multilevel inverters and compares it with other modulation strategies to address Total Harmonic Distortion (THD). MLIs are able to generate high-quality voltage waveforms, but they often suffer from THD, which can affect system performance. The paper reviews various modulation strategies, including Space Vector Modulation (SVM), various SPWM techniques, analyzing their effectiveness in reducing harmonic distortion. SVM is highlighted for its ability to optimize switching patterns, significantly reducing THD and improving waveform quality. The review encompasses simulation results for each technique. By providing a comparative analysis, the paper offers insights into how different modulation methods can enhance the efficiency and performance of power conversion systems across various industrial applications.
