An enhanced output voltage compensator for inverter under nonlinear load and voltage distortions

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 imp...
