A Single-Phase Switched-Capacitor Nine-Level Inverter With Reduced Capacitance

Zhuyu Xun et al.

Summary: A novel nine-level switched-capacitor multilevel inverter with reduced capacitance and balanced capacitor voltage is proposed in this article. It utilizes only two capacitors to boost the input voltage and achieve nine output voltage levels under different load conditions. The proposed inverter eliminates the capacitor voltage imbalance by charging or discharging the capacitors independently. The theoretical analysis, simulation, and experiment results validate the feasibility of the proposed inverter.
