Design and realization of a photovoltaic system equipped with the analogical and digital MPPT command for better exploitation of solar energy

In this paper, we present results concerning the design, implementation and modeling of photovoltaic systemprototype (PV) equipped with an analog or digital MPPT command. This MPPT command is provided withan analog circuit that detects a dysfunction of the system while ensuring the optimal operation of the PVsystem without restarting the system. The experimentation of the PV system carried out shows the possibilityto following the maximum power point (MPP) of PV panel independently to rapid changes of weather (Solarirradiation…) and load (battery, resistor…). In the case of analog MPPT command, every divergence of thePV system, the circuit detects the perturbation and CDCS circuit reconvergence the system without restartingit to the new PPM.
