摘要
输出滤波器OF(Out Filter)对并联有源滤波器的谐波补偿能力有不可忽略的影响,然而目前对这方面的研究较少。文章在对OF的结构和工作原理进行分析的基础上,提出一种OF参数设计及优化方法,通过对非线性负载补偿特性的仿真和实验分析,验证了该方法的正确性。采用该方法设计的OF,能有效地滤除高次谐波,提高了APF的工作效率。
Although the output filter(OF) influences the compensating ability of active power filters(APF), few study focused on it. The paper presents a parameter design and optimization method of OF based on the analysis on its structure and principle. The simulation and experiment result of non-linear load compensation performances has verified that the proposed design method is feasible. OF selected by this method can eliminate effectively high frequency harmonics and enhance the efficiency of APF.
