Abstract: To solve the problems of existing nonisolated PV grid-connected inverters, such as leakage current, power pulsation, and harmonic current, a single-phase common-ground-type nonisolated ...

Abstract: In this research study, a photovoltaic (PV) interface three-level Neutral Point clamped (NPC) voltage source inverter-based three-phase Shunt Active Power Filter (SAPF) has been proposed.
