A 17-Level Single DC Source Switched-Capacitor-based Multilevel Inverter with Self Voltage Balancing

In this paper, a novel switched-capacitor multilevel inverter with boost capability is proposed. The presented topology consists of one DC source, one diode, 19 power switches, and 3 capacitors, which can produce 17 separate output voltage levels. This topology has several notable advantages, including high voltage gain, low switch voltage stress, and voltage self-balancing ability. A performance study of the proposed topology, as well as theoretical calculations, is provided. To highlight the advantages of the proposed structure, a comparison between traditional inverters and the proposed inverter is made. Finally, the simulation results are extracted to demonstrate the performance of the proposed topology and the correctness of the theoretical relations.
