The present work investigates a real time implementation of a photovoltaic grid connected chain, based on fuzzy logic MPPT controller (FLC). The implementation is realized on a dSPACE 1104 single board, controlling a boost chopper in the PV array side and a VSI inverter in the grid side. The FLC tracks permanently the maximum power point of the PV array without any prior information on the syst...
