【Abstract】 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.更多还原
