摘　　要：现有的输出滤波器(Output Filter,OF)参数设计大多以工程经验选取为主,没有考虑输出滤波对有源滤波系统的补偿能力和补偿性能的影响。本文综合考虑了输出滤波器的输出补偿谐波能力和滤除开关谐波能力等性能要求,在并联型有源滤波器的框架内,提出了一套输出滤波器参数设计和优化的方法。仿真和实验结果表明,该方法可以提高逆变器的工作效率达50%左右,证明了该方法的有效性。The design method of output filter （OF） mainly depend on engineering experience,that does not include the influence of OF to the compensating ability and property of the whole system.In the frame of parallel active power filter,this paper presents a frequency-varying design and optimization method for OF that takes output ability and retraining ability as objectives.The simulation and experimental results demonstate that the optimization method enhance efficiency of inverter to about 50 percent, confirms the correctness and validity of the proposed method.
