Conception, modélisation et réalisation d’un système photovoltaïque de moyenne puissance

In this paper we have analyzed the design, the modelling and the realization of a photovoltaic system (PV) of average power (100 W). Since the optimal tension on the outlet side of generator PV depends very little on illumination, and then we used a MPPT command of the type 'Loops control of the voltage'. The results obtained show that system statement thus conceived and carried functions under the optimal conditions independently of the variations weather and the load. The various experimental results obtained are in very good agreement with those obtained in the Pspice simulator.
