摘要：

This paper investigates the feedforward schemes of grid voltages for a three-phase LCL-type grid-connected inverter. The full-feedforward functions of grid voltages are derived for the stationary alpha - beta frame, synchronous d - q frame, and decoupled synchronous d - q frame-controlled three-phase LCL-type grid-connected inverters. The derived full-feedforward functions mainly consist of three parts which are proportional, derivative, and second derivative parts. The use of the traditional proportional feedforward function in the three-phase LCL-type grid-connected inverter will result in the amplification of the high-frequency injected grid current harmonics. With the proposed full-feedforward schemes, the injected grid current harmonics and unbalance caused by grid voltages can be greatly reduced. The effectiveness of the proposed feedforward schemes is verified by the experimental results.
