摘要
功率因数校正技术是抑制谐波电流、提高功率因数的行之有效的方法,近年来受到了越来越多的关注。本文在论述有源功率因数校正基本原理的基础上,对有源功率因数校正的主电路拓扑及控制方法进行了分析与比较,总结其特点;对无源功率因数校正(PFC)电路、有源两级功率因数校正(PFC)电路和有源单级功率因数校正(PFC)电路进行了分析及性能比较,指出它们分别适用的场合。
Power factor correction technology is an effective method of restraining harmonic currents and increasing power factor, which has been attended more and more in recent years. Main circuit topologies and control methods are analyzed and compared on the basis of the principle of active power factor correction （ APFC ）, which characteristics are summarized. Passive power factor correction circuit, two-stage and single-stage APFC circuits are researched, which applications are given by comparison of their performance.
