Design and Analysis of a Switched Capacitor Inverter for EV

Abstract

Abstract: This paper focuses on the switched-capacitor converter configurations for a wide range of applications, which have numerous stages which are designed for different voltage levels. A single-phase switching capacitor multilevel boost inverter topology configuration with fifteen levels is discussed using fewer switches and a voltage boost gain. The main goal of this work is to develop a 15L multilevel inverter that can provide AC output voltage with minimal harmonic distortion. The output THD decreases to zero as even the level number approaches infinity.
