摘　　要：开关电源大规模地应用,使得电网电流波形严重畸变,因此研究满足强制性电磁兼容标准的APFC技术具有重要意义。设计了一款基于Boost变换器的具有APFC功能的开关电源电路,并在MATLAB/SIMULINK中建立了双闭环控制系统仿真模型。仿真结果表明:Boost型APFC电路能够达到高输入功率因数,抑制谐波的目标。Switching power supply application on a large scale,and grid current waveforms distortion harder and harder,So it is of great significance in APFC research to meet mandatory electromagnetic compatibility standars. This paper designed a practical switching power circuit with the function of APFC,and established simulation model of double closed-loop control system based on Matlab/ Simulink.Simulation results proved that the Boost APFC rectifier can achieve good performance of high power factor,few harmonic.
