Abstract

This study enhances the buck-boost modular converter topology, also known as the Y-voltage source inverter, by implementing a control strategy that simultaneously manages active power injection into the grid while functioning as a shunt active power filter. Each phase-module operates as an independent buck-boost dc-dc converter, allowing the converter to accommodate wide variations in photovoltaic (PV) voltage. The control strategy is derived from instantaneous id-iq power theory and employs a dead-beat-type current control, which is developed and validated. Simulation tests confirm the converter's efficiency as an Active Power Filter (APF) under unbalanced and distorted grid voltage conditions.
