摘　　要：本文提出了一种三相单开关升压型有源功率因数校正器的新型控制方法。该方法不需电流检测,而能实现开关管的变频率控制,使得输入电流工作于准临界连续状态,减小了输入电流的谐波含量。A novel control mode of single switch three phase power factor corrector is presented. In this mode,system is operated in variable switching frequency without any current measurement. And the input current is operated in quasi-critical continuous mode,which has a better hamonics distortion.
