Self-Balanced Switched-Capacitor Thirteen-Level Inverters With Reduced Capacitors Count

Yuanmao Ye et al.

Summary: This letter describes two improved 13-level inverters based on switched-capacitor. Compared with their original structure, which is published recently, one less high-voltage capacitor is required in the proposed inverters and the blocking voltage of their inverting half-bridge is reduced by half. In addition, the new inverters inherit various advantages of the original structure, such as a high boost factor of 6, self-balanced capacitor voltages, and reduced voltage ripples. The feasibility of the proposed inverters is finally verified by experimental results.
