Self-balanced high gain switched-capacitor boosting inverter with lower cost function

This paper discusses in detail a new 17-level inverter that employs a switched-capacitor (SC)-based configuration. The proposed SC-based inverters require just a single DC power supply, three capacitors, four diodes and 13 switches. The peak inverse voltage of the proposed 17-level SC-based inverter half-bridge is cut in half when compared to the prior arrangement, which was published not long ago. The blocking voltage is reduced by an order of magnitude as well. Many of the features of the proposed SC-based inverter, such as a high boosting gain factor (G) of eight times, self-balanced capacitor voltage and decreased voltage ripples in capacitors, have been carried over to other SC-based MLIs. The circuit description, working theory, PWM modulation techniques and capacitor voltage ripples are all examined. Finally, the results of the experiments show without a doubt that the proposed SC-based inverter can be made.
