一种新型软开关PFC电路的分析与仿真

A Sort of New Pattern Soft Switch PFC Circuit Analyze and Simulink

本文引入了一种新型的软开关PFC电路,文中首先分析了开关电源的发展历程,说明了谐波对公共电网的危害,接着给出了这种软开关PFC的电路拓扑并对其工作原理进行了分析,最后对其参数进行设置,用Matlab软件进行仿真,并得到了良好的电压-电流波形,而且减小了电路的损耗,提高了电路的效率,实现了小型化,绿色化的要求。

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.
