초록

The paper discusses the influence of a grid impedance, especially for a leakage inductance of a grid side transformer. The grid impedance does not usually take into account during the design stage of the current controller. As a result, low order harmonics in the grid current are distorted. In this paper, the active feed-forward compensation method is proposed for the purpose of attenuating the current distortion. The proposed method can be applied to L filter as well as LCL filter. The effectiveness of the method is verified through various simulations and experiments based on a 1.5kW voltage source inverter prototype.
