Harmonic Current Suppression Strategy for Grid-Connected PWM Converters With LCL Filters
As for Boxes (Set of 3) a grid-connected PWM converter with LCL filter, harmonic current can flow freely into the grid-side inductor and filter capacitor, when the connected power grid is harmonically distorted.The fact lies in that the conventional control scheme has a little ability to suppress the grid current harmonics.Though the harmonics can
