| Abstract: | A synthesized control scheme combined an improved repetitive control with PI control for single grid-connected inverter is introduced.Repetitive control is used to reduce steady-state grid-connected current wave distortion and PI con-trol can improve the dynamic performance of the system.Simulation and experimental prototype for a single-phase grid-con-nected inverter controlled by TMS320F2812 are presented to verify the performance of the proposed control approach.The results prove that the harmonics in th... |
