Abstract

This paper presents a phase-shift control method for double-wing multilevel modular switched-capacitor dc-dc converter (DW-MMCCC) to achieve output voltage regulation and zero voltage switching features. By utilizing the circuit stray inductance and the proposed phase-shift control method, the output voltage of DW-MMCCC can be controlled without sacrificing efficiency significantly. The DW-MMCCCs with odd conversion ratio and even conversion ratio are analyzed separately. Simulation results are provided to demonstrate the validity of the proposed method. A 500 W prototype is built; and experimental results is provided to validate the proposed operating method.
