逆变器输出滤波器的设计

Design of Inverter Output Filters

首先分析了逆变器输出滤波器OF的基本类型和现有的设计方法,指出OF类型选择的盲目性依然存在,揭示了OF影响有源滤波器性能的原因。在此基础之上,建立描述OF对有源滤波器影响的性能指标函数,并给出了不同类型OF的性能指标函数。最后进行了OF对有源滤波器性能影响的仿真实验,说明输出滤波器OF对提高有源滤波器的滤波效果和抑制高频毛刺的意义。

Basic types of inverter output filters and the existing design methods are analyzed, and the impacts of the output filter on APF performance are revealed. Then, the performance index functions to describe the impacts are proposed, and the index functions for different types of inverter output filters are given. Simulation experiment is conducted to reveal the impacts of the output filter on the performances of APF in improving the filtering effect of APF and suppressing high-frequency burrs.
