本文讨论了一种用于并网三相 PWM 电压源逆变器 (VSI) 的 LCL 滤波器的设计方法。通过分析逆变侧电感电流的总谐波失真（THDi）和通过LCL网络注入电网的电流（RAF）的纹波衰减系数，可以明确LCL的参数设计。通过仿真和实验，目标​​电流THD与实际电流THD具有良好的一致性，验证了所描述的LCL滤波器设计方法。
This paper deals with a design method of LCL filter for grid-connected three-phase PWM voltage source inverters (VSI). By analyzing the total harmonic distortion of the current (THDi) in the inverter-side inductor and the ripple attenuation factor of the current (RAF) injected to the grid through the LCL network, the parameter of LCL can be clearly designed. The described LCL filter design method is verified by showing a good agreement between the target current THD and the actual one through simulation and experiment.
