摘要：简单介绍了传统混合有源滤波器无源部分存在基波阻抗不高、倒送无功电流大等缺点，并不适合在电网高功率因数条件下进行谐波补偿。通过对传统混合有源电力滤波器无源部分的研究和改进，提出了一种新型混合有源电力滤波器拓扑。这种拓扑与传统混合有源滤波拓扑相比，具有低无功倒送、滤波特性良好、所用无源器件少等优点，弥补了传统混合有源滤波器不适用于低压配电网高功率因数条件下谐波电流补偿应用的缺陷，使混合有源滤波器具有更加广泛的应用前景。

Abstract: A simple study on traditional hybrid active filter was introduced, which was not suitable for harmonic compensation in high power factor conditions due to the high fundamental impedance and the large additive reactive current injection. Then a new topology of hybrid active power filter with improved passive filter was proposed. Compared with the traditional one, the new topology has the advantages include reducing the reactive current injecting into the main grid, having better impedancefrequency characteristic, using fewer passive component, makes up the deficiency used in high power factor circumstance, and owns a brighter future.
