摘要

混合有源滤波器是一种有效的谐波抑制方式。电力系统中谐波源负载种类繁多，特性各异，针对目前应用最为广泛的三相整流桥负载，在以往混合滤波器研究的基础上，提出了一种新型单调谐混合滤波器，对其无源滤波部分依据有源部分容量最小的原则进行了设计，并对其工作原理进行了详细的分析研究。针对所设计的混合滤波器的特有结构，设计了其复合控制策略。该复合控制策略在不影响系统稳定性的基础上，提高了系统的滤波性能，保证了有源滤波器小容量下良好的运行性能。对所设计的复合控制器在频域和时域内进行了稳定性分析。仿真和实验结果验证了所提出的拓扑结构和复合控制策略的有效性。

Abstract

Hybrid power filter has been proved to be a useful approach to eliminating current harmonics caused by nonlinear loads. Nowadays， there are various harmonic source nonlinear loads. This paper proposes a novel shunt hybrid power filter to attenuate current harmonics due to three-phase rectifier bridge loads， which are most popular in industry use. A novel design method for the passive power filter is proposed to minimize the rating of the active power filter. Furthermore， a combined controller is designed according to the novel hybrid topology， which contributes to both filtering characteristics and system stability. The stability of the combined controller is analyzed in the time and frequency domain in detail. The validity and effectiveness of the system have been verified by simulation and experimental results.
