摘　　要：新型电力滤波器采用有源滤波器与LC无源滤波器串联后再与电网并联的混合结构,本文通过理论分析和matlab/simulink仿真分析,验证了有源滤波器与LC滤波器相串联既克服有源电力滤波器容量大、成本高因而缺乏工程意义的缺点,同时改善了滤波,抑制了并联谐振。本文还对有源滤波器的输出滤波器进行了参数设计和仿真,改善了整个系统性能。A new type of power filter with hybrid structure of an active filter and a LC filter connected in series is parallel connected to the network. Based on theoretical analysis and Matlab/Simulink simulation, this paper verifies that an active filter and a LC filter being connected in series can not only overcome the disadvantages of the active filter which has large capacity, high costs and is short of engineering meaning, but also improve the filtering and suppress the parallel resonance .In addition, this paper performs parameter designing and simulating for the output filter of the active filter, which improves the performances of the whole system.
