| Abstract: | LCL-filter in grid-connected inverter is characterized by better gain at low frequency and better attenuation at high frequency. It is difficult to define parameters. This paper proposed a design method of the LCL- filter parameters on shunt active power filter. Then, based on the total inductance, its distribution and the influences on system control were analyzed. A matching and optimization method of the LCL-filter was proposed. The simulation and experiment validated the feasibility of this method. |
