摘要
电器设备的功率因数过低对电网造成的不利影响日益受到人们的重视。功率因数有源校正技术因此而迅速兴起。本文介绍功率因数校正（ＰＦＣ）原理，以及一个ＰＦＣ整流器的实现。
More and more attention is now being paid to the negative influence of the low power factor of electric apparatus on the power network and the technique for correcting the power factor is being developed. This paper discusses the principle of power factor correction (PFC) and describes the realization of a PFC rectifier.
