摘要
针对当下一些接入电网的用电设备如电动汽车充电机系统功率因数低、谐波污染大等问题,引入了一种基于CSC变换器的APFC拓扑电路,并对其进行了分析研究。为提高用电系统功率因数,同时实现母线电压可调,采用了DCM模式下的CSC控制方式,通过搭建MATLAB模型获得仿真结果并搭建实物平台进行实验验证,证实了在电动汽车充电机系统中采用基于CSC变换器的APFC拓扑电路可有效降低其谐波产生,并实现功率因数校正的功能。
Aiming at the problems of low power factor and harmonic pollution in power equipment such as charging pile of electric vehicle,in this paper,an APFC circuit based on CSC converter was introduced and analyzed.In order to improve the power factor of the motor power system and realize adjustability of bus voltage,the CSC control method working in DCM mode was adopted.The simulation results were obtained by constructing the MATLAB model and the physical platform was built to verify the simulation results.It was proved that the APFC circuit based on CSC converter can effectively reduce harmonic generation in charging pile system and realize the purpose of power factor correction.
