This paper proposes a photovoltaic (PV)-based three-phase four-wire (3P4W) series hybrid active power filter (SHAPF) it comprises of a series active power filter (SAPF) and an LC shunt passive filter. The proposed system eliminates both the current and voltage harmonics and compensates reactive power, neutral current and voltage interruption. A SAPF demands a source of energy for compensating the voltage sag/swell. This system introduces a new topology for SHAPF utilizes the PV with DC–DC boost converter as a source of DC power for SAPF. The compensation current reference evaluation is based on the twin formulation of the vectorial theory of electrical power theorem with fuzzy logic controller (FLC). The PV array/battery managed DC–DC boost converter is employed to step up the voltage to meet the DC bus voltage requirement of the three-leg voltage source inverter (VSI). The foremost benefit of the proposed system is that, it will provide uninterrupted compensation for the whole day. This system utilizes the renewable energy accordingly saves the energy and shares the load during the solar irradiation available. The simulation and experimental studies are carried out to validate the effectiveness of the proposed PV-SHAPF.
