Description	In the same filtering effect, the single-phase photovoltaic grid-connected inverter with L-type filter needs large inductance, and the traditional PI controller of gridconnected inverter can't obtain zero steady-state error. A Quasi-PR control strategy by using LCL-type filter with current control outer loop based on grid current and current control inner loop based on capacitor current is proposed in this paper, which increases system damping, restrain oscillation and improves the stability of system. On this basis, the control system is modeled and analyzed, as well as the parameters are designed. The simulation model is designed to verify the theoretical analysis under MATLAB/Simulink. The results show that the grid current distortion rate is smaller, the grid current can be tracked with zero steady-state error, and the system output meets the requirements of grid.
