| 中文摘要:传统的LCL型滤波器抑制高频谐波的速度快，LLCL型滤波器内有串联谐振支路，能使开关频率谐波旁路。针对三相逆变并网系统并网电流的班开关频率谐波问题和高频谐波问题，本文提出一种新型的LCLCL型滤波器。通过在拓扑结构上结合LCL型滤波器和LLCL型滤波器中的串联谐振支路，并对滤波器参数进行规范设计，以达到更好的滤波效果。最后进行三相逆变并网仿真，验证了LCLCL型滤波器优越的正确性和有效性。 |

| Abstract:The traditional LCL type filter can suppress the high frequency harmonics，and the LLCL filter can make the switching frequency harmonic bypass. In view of the class switching frequency harmonics and high frequency harmonics of the grid connected current of three phase inverter，this paper proposes a new type of LCLCL filter. By combining the LCL type filter and the LLCL type filter in the series resonant branch，the filter parameters are designed to achieve a better filtering effect. Finally，three phase inverter simulation is carried out to verify the correctness and effectiveness of the LCLCL type filter. |
