Abstract

This paper presents a control scheme of the shunt active filters using the source current detection to suppress the source current harmonics. The proposed control scheme can minimize the source current harmonics under the given active filter capacity, which can be realized by adjusting the magnitude and phase of the compensation current using the complex compensation gains in the frequency domain. The effectiveness of the proposed control scheme has been verified by experiments. As a result, the good effect on the compensation for the source harmonic currents in the proposed control scheme is obtained compared with that in the conventional one.
控制有源滤波器使用源电流检测
提出了一种利用源电流检测抑制源电流谐波的并联型有源滤波器控制方案。在给定有源滤波器容量的情况下,该控制方案可以通过在频域利用复补偿增益调节补偿电流的幅值和相位来实现源电流谐波的最小化。实验验证了所提控制方案的有效性。结果表明,与传统控制方案相比,该控制方案对源谐波电流的补偿效果较好。
