Résumé : A single-stage three-phase Photovoltaic (PV) in-verter guaranteeing Maximum Power Point Tracking (MPPT) and nearly unitary Power Factor (PF) in the connection to the Low Voltage (LV) grid, while acting as an Active Power Filter (APF), is developed in this paper. A Current Source Inverter (CSI) with an inductive DC link is used to connect the PV array to the grid, and the MPPT is achieved controlling directly the power in the DC link. Based on the power balance of the whole system, the grid current references are generated in a dq frame synchronized with the grid guaranteeing the mitigation of current harmonics produced by a non-linear load connected to the grid. Simulation results are presented to confirm the proper operation of the system.
