摘要
研究了一种基于纹波电流前馈的单相并网逆变器的电流控制方法。首先研究了适用于单相并网逆变器的传统有限集模型预测控制算法(FCS-MPC)。随后研究了输岀电流的纹波特征,接着通过改进传统的有限集模型预测控制算法,在此基础上增加了前馈纹波电流环节,以达到降低单相并网逆变器输出电流纹波的目的。最后通过仿真和实验,证实了所提控制方法的有效性。
A current control method for grid-conneccted inverters is studied. Firstly, the finite control set model predictive control (FCS-MPC) of the single-phase grid-connected inverter is investigated. Secondly, the characteristics of the output current ripple are studied and the output current ripple of the single-phase gridconneccted inverter is reduced through improving the traditional finite set of model predictive control with a feedforward control of the current ripple. Finally, simulation and experimental results verify the performance of the proposed control method.
