摘　　要：针对LCL滤波器谐振产生的零阻抗问题,采用基于加权平均电流的控制策略,但其在同步旋转坐标系下仍有强烈的耦合关系,不便于对系统控制,因此电流环将采用前馈解耦控制的策略,实现对d轴和q轴的独立控制,系统具有较高的功率因数,最后通过仿真验证了该方案的有效性。For the zero resistance caused by the LCL filter,a weighted average current control scheme is adopted.However,it has coupling,and is,difficult to control. The current loop adopts a feed forward decoupling scheme and is adopted to alleviate the problem. In this method,two axies can be controlled,respectively,and the system has a high power factor. The simulation verifies the effectiveness of this scheme.
