Abstract
The performance of LCL filter for single-phase grid-connected inverter depends mainly on its parameter design, but the classic method has some shortcomings. Firstly, the inefficiency from repeated trials. Secondly, maybe the results obtained can be adapted to the requirements of grid-connected harmonics, but it's not the optimal solution when considering high frequency harmonic suppression effect and filter cost volume. This paper proposed a relatively precise parameter design method for LCL filter to keep high frequency harmonic distortion and filter volume both appropriate. The accuracy of the proposed parameter design method is verified by simulation.
