Research on single-phase parallel hybrid active power filter

提出一种新型单相并联混合型有源滤波器的拓扑结构,分析了其基于磁通补偿和谐波分流技术的原理,在无源部分只装设双调谐滤波器的情况下,与传统并联混合型滤波器相比较,有源滤波器(APF)所需容量大大减小;采用检测相地间谐波电压的控制方式,并进行相应的仿真研究。结果表明,新型单相并联混合型有源滤波器滤波效果好,控制方式可行,有源滤波器所需容量很小。

This paper presents a novel topology of single phase hybrid parallel active filter and analyzes its principle based on the magnetic flux compensation and the harmonic divergence technology. Compared with that the traditional hybrid parallel active filters are conducted in the circumstances of installing the double-tuned filter only, the result indicates the capacity of APF is greatly reduced. The corresponding simulation researches are conducted by use of the control mode of measuring the harmonic voltage between phase to ground. The result indicates the filter effect of the new single-phase parallel hybrid active filter is good, the control mode is feasible, and the active filter capacity required is very small.
