Abstract This paper proposes a novel switching capacitor PWM DC-DC voltage regulator module. The converter is a combination of a switching capacitor converter and a PWM converter, and it has the following advantages: ①Zero voltage switching of all the MOSFETs. ②Using an auto transformer self-driven method to save the driver loss and the synchronous rectifier (SR) body diode conduction loss. ③Its efficiency is not sensitive to leakage inductor, so that the discrete transformer can be used to save the cost. ④Single phase option makes it more flexible. A four-phase 700kHz 1.2V/130A output VRM prototype was built to verify the analysis.

Key words： Switching capacitor converter PWM converter self-driven zero voltage switching
