摘要
介绍了交错PFC电路的基本类型和工作原理以及一些扩展的单相交错PFC电路。最后分析了交错PFC电路的优缺点。
By using interleaving technique in single phase PFC,the input current ripple of the PFC circuit can be effectively reduced,power factor will increase,and the size of front end EMI filter can be smaller.This paper introduces the basic topologies of interleaved PFC and explains their operating principle in brief.Several extended topologies are given.Finally,the advantages and disadvantages are given in the conclusion.
