摘要
为了提高电动汽车直流充电桩的功率因数,对有源功率因数校正(APFC)方法进行研究。采用电压电流双闭环控制策略,使整流后的电流与电压变形同频同相,达到了较高的功率因数甚至接近于1;利用Matlab仿真模型验证了控制策略的正确性。
In order to improve the power factor of DC charging pile, the power factor correction method is studied in this paper.With the voltage and current double closed-loop control strategy,which makes the rectified current and voltage deformation with frequency and phase and reached a higher power factor,even close to 1.Matlab simulation is built to verify the correctness of the control strategy.
