description This paper focuses on voltage source inverters used in new energy user power supply and energy storage power supply systems. If it is equipped with linear load, the power quality of output voltage can be easily guaranteed. If it is equipped with a nonlinear load, the system is affected by output impedance, and the output voltage is easy to be distorted. In this paper, the mechanism of output voltage distortion of inverter with a nonlinear load is studied. It is concluded that the distortion is caused by the voltage drop of nonlinear load current in the output impedance of the inverter. We proposed an embedded repetitive control compensator to improve the output voltage quality. In addition, we give out the Bode diagram parameters select method. The simulation results show that the proposed control strategy is feasible and effective.
