摘　　要：功率因数校正技术(Power Factor Correction,PFC)是中大功率电子设备不可或缺的部分。因此,提出了一种基于单周期控制的新型无桥Buck PFC变换器,分析了变换器的工作原理和单周期控制策略,然后采用PSIM仿真软件进行验证。仿真结果表明变换器能实现降压输出,并且能减小输入电流死角,改善了功率因数校正的效果。Power Factor Correction(PFC)technology has become an indispensable part of medium and high power electronic equipment.In this paper,a novel bridgeless buck PFC converter based on one cycle control is proposed.This paper first analyzes the working principle and single cycle control strategy of the converter,and then verifies it by PSIM simulation software.The simulation results show that the converter can achieve buck output,reduce the dead angle of input current and improve the effect of power factor correction.
