Abstract: This text introduce a sort of new pattern soft switch PFC circuit .First, analyze the develop course of the on-off power supply. Second, relate the harm of humorous wave to the commonality electricity net. Third, present the topology and the principium chart of the soft switch PFC and analyze it .At last ,set the parameter and simulates the converter of with matlab simulation. more over ,get the hold of well voltage and current wave , minish the spoilage of the circuit, enhance the efficience of the circuit, meet the demand of the miniaturization and viridity.
Keyword:on-off power supply soft switch PFC MATLAB miniaturization viridity
