A Novel Multi-Level Inverter for Renewable Energy System Applications

Abstract

This article proposes a new multi-level inverter using switch-capacitor structure which works based on switching capacitor on series/parallel in the circuit through the switches. This configuration reduces the number of components include semiconductor switches, diodes and input source than the traditional inverters, thereby reducing the cost and the size of the system. The proposed inverter uses two capacitors, two diodes and nine switches to create a nine-levels voltage output. In this paper, the simulation results are implemented by PSIM 9.0 software and the experimental results are shown.
