给出了单相电力有源滤波器的一种新的控制算法：负荷有功分量法．使用该算法的单相电力有源滤波器，对对称和非对称负载产生的谐波具有较好的抑制作用，在电源电压畸变的情况下，也能保证负载电源侧电流为正弦波．样机实验表明，该滤波器具有较好的滤波特性．

A new algorithm based on calculation of the real part of the fundamental load current is proposed for a single phase active power filter.The algorithm proposed can maintain the input power factor of the mains colse to unity and force the mainscurrent to be a sinewave under distorted or nondistorted mains voltage.A prototype is developed and is tested to verify its performance.The experimental results show that the filters have good capability.
