摘要
利用Matlab/Simulink搭建单极性SPWM控制单相并网逆变器模型来分析并网电流产生过零点畸变的原因,提出了一种消除过零点畸变的动态补偿算法,并具体介绍了动态补偿算法的实现步骤。实验结果证明:动态补偿算法能完全解决单相并网逆变器中存在的过零点畸变问题。
By making use of Matlab/Simulink to build a unipolar SPWM control model of single phase grid-connected inverter,this paper analyses the reasons of zero-crossing distortion for the grid-connected current and proposes the dynamic compensation algorithm,together with detailed operational steps,to eliminate zero-crossing distortion.The experimental results show that the dynamic compensation algorithm can completely solve the problem of zero-crossing distortion in the single phase grid-connected inverter.
