A Comparative Analysis of a Multilevel Inverter Topology Based on Phase Disposition Sinusoidal Pulse Width Modulation.

A Multilevel Inverter (MLI) meets the power requirements of most power electronic applications. It can provide an AC supply with better power quality. The higher number of levels in an MLI results in better power quality output. The fundamental question that comes to mind is what the optimal number of levels can be in designing an MLI for better performance. This paper aims to provide a comparison of three-, five-, and seven-level schemes based on a "Diode Clamped MLI" and will analyze their performance on the reduction of Total Harmonic Distortion (THD).
