Abstract

A novel isolated switching capacitor regulator is proposed in this paper. The converter is the combination of a switching capacitor converter and a PWM regulator. The proposed converter has the following advantages: 1) Fast transient response and the output voltage can be regulated as well. 2) The main switches achieve zero-voltage-switching and the rectifier diode realizes zero-current-switching. 3) Self-driven synchronous rectifier can be employed to improve efficiency; 4) Achievement of electrical isolation and multiple-output. A 200W hardware was built to verify the analysis.
