摘要

基于单级软开关有源功率因数校正(APFC)的正激变换器具有许多优点。首先它具有高的功率因数，其次功率开关可以实现软开软关，因此大大提高了变换器的效率，但是输出中存在100Hz的谐波。本文采用一种典型的PID控制方法对谐波进行了滤波。

Research on Avoiding 100Hz Harmonic in Single-stage Soft-switch Active Power Factor Correction

The forward converter based on single-stage soft-switch active power factor correction (APFC) has many advantages. First of all, it has high power factor, secondly, the power switches can achieve soft-open and soft-shutdown, so efficiency of the converter is greatly improved, However, there are 100Hz harmonics in the output. A typical PID control is successful used to filtering of the harmonics in this paper.
