Abstract
International audienceDue to the rising fuel costs and growingworldwide demand for electricity, renewable energy sourcesbecome a necessity rather than a luxury. This paperpresents an original control strategy for a buck-boost basedconverter used as a low cost inverter in a photovoltaic (PV)system. The main objective of the inverter is to harvestmaximum power from the PV module and to inject it intothe grid. The design of the converter is detailed and,together with the control method, a macro-model for theinverter is proposed. The macro-model is developed in orderto have shorter simulation times and test various maximumpower point tracking (MPPT) algorithms. Simulations andexperimental results validate the proposed PV system
