研究生期间完成的有源电力滤波器仿真（APF）,采用电流内环，电压外环的双闭环控制方案。同时，交流测滤波电感经过了精心设计，滤波效果很好。(Graduate students during the simulation of active power filter (APF), the completion of the current loop, double closed loop control scheme of voltage outer loop. At the same time, the AC side inductance by design, a very good filtering effect.)
