Control of Photovoltaic System Connected Directly To The Grid by a 3-Phase BOOST Inverter

For PV applications, many studies focus on maximum power extraction without evaluating losses in the conversion chain. As part of this research, it is proposed to evaluate a direct energy conversion solution from the panel to the network without intermediate stages or transformers. The structure is presented as a 3-phase boost inverter integrating the maximum power extraction function (MPPT) while ensuring control of the power fed into the grid. A precise assessment of the losses will be carried out and an evaluation on the different components will be compared. The operation will be studied in particular according to the power rating and the switching frequency.
