In this paper, a new control method based on fuzzy logic controller is proposed tocontrol the maximum power point tracking of photovoltaic system (PV) in a hybridphotovoltaic/fuel cell (FC) system. The purpose of the maximum power point trackingcontroller is to shift the actual voltage of PV to the optimum voltage. In the hybridsystem, the FC is running in normal condition, that is the voltage of FC is not shiftedby converter, the voltage of FC is just influenced by demand. When PV produces themaximum power, the fuel consumption can decrease. The proposed method maximizesthe PV power by shifting the voltage to the optimum voltage of PV with consideringthe voltage of FC, because the voltage of PV must be same with the voltage of FC inorder the PV can transfer the power to the demand well, that can not be done using P&O method because P &O method does not consider the voltage of FC. Theconfiguration of PV and FC in hybrid system is in parallel, If the voltage of FC ishigher than the voltage of PV, The PV can not transfer the power well to the demand,if the voltage of PV is higher than the voltage of FC, the FC can not transfer well tothe demand. From the simulation, we can see that the power of hybrid system withproposed method is in the maximum power comparing with P &O method and hybridsystem with proposed method can save average 10.46 % of fuel and 10.57 % of Aircomparing with using P &O method.
