本文对三相并联电力滤波器的输出LC滤波器进行了研究,考虑有源滤波器的输出电流的频宽和EMI标准对LC滤波器的参数进行设计,并给出了设计实例,仿真结果验证了设计方法的可行性。

This paper presents the results of study on electric power output filter in a 3-phase parallel connection circuit. An example is given of how to design a LC output filter, provided that the frequency band width of output current of a LC filter and its EMI effect are stipulated as pre-conditions. The feasibility of the proposed design method has been certified by the positive result of emulation.
