An active feedforward compensation for a current harmonics reduction in three-phase grid-connected inverters

Abstract

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… (More)
