Phase shift control of zero-voltage-ripple rectifier

As miniaturization of electronic device and complication of communication system progressed, downsizing and high efficiency are desired on power circuits. A zero-voltage-ripple rectifier can miniaturize the LC low-pass-filter, because its circuit structure negates AC components of switch current which causes output voltage-ripple. In this paper, we propose a phase shift control of a zero-voltage-ripple rectifier in order to control the zero-voltage-ripple rectifier at fixed frequency. Experimental results are given.
