The invention discloses a power factor corrector. A continuous current power factor correction working mode is realized by using series connection of a forward transformer and a power factor correction inductor. The efficiency of the power factor corrector is improved by using the primary blocking diode reverse leakage current of the forward transformer, and simultaneously the primary coil electric energy of the forward transformer is released by using an electric energy release coil of the forward transformer, so that the voltage of a switch tube is reduced, and the soft switching working mode of the switch tube is realized by using a small capacitor. 本发明为功率因数校正器，利用正激变压器与功率因数校正电感串联,实现连续电流功率因数校正工作方式.利用正激变压器的初级阻止二极管反向漏流提高功率因数校正器的效率,同时用正激变压器的电能释放线圈释放正激变压器的初级线圈电能,以降低开关管的电压.用小电容实现开关管的软开关工作方式。
