Inverse Polarity Resonant Switched-Capacitor Converter with ZVS Operation and Full-range Regulation

A new full-range regulation method for inverse polarity resonant switched-capacitor converter is proposed under all load conditions. The converter with fixed on-time pulse frequency modulation is highlighted as an example to implement the proposed method, which features the benefits of full-range voltage regulation, ZVS turn-on for switches and ZCS turn-off for diodes. Experimental results are presented to support the proposed full-range regulation method.
