Regulation of electric power provided by photovoltaic panels systems

Abstract

In this article we analyzed the design in Pspice and carried out a photovoltaic system (PV) of average power (100 W). In this system the operation of generator PV is controlled by an analog command MPPT and a DC/DC converter (Boost). In the case of two batteries (12 V, 115 Ah) in series, we showed that the generator PV functions instantaneously under the optimal conditions independing of the solar radiation variation, and that the converter efficiency is very satisfactory (about 90%). The whole of the results show in one hand very an good agreement between the results simulated in Pspice and those experimental, and in the other hand the possibility of using system PV in an installation PV.
