A fuzzy maximum power point tracker (MPPT) for improving the charging performance of photovoltaic systems is proposed. Fuzzy input parameters dI/dP, ∆dIdP and variation of duty cycle (∆DC) are used to generate the optimal MPPT converter duty cycle and a suitable battery charging rate, such that solar panel maximum power is generated under different operating conditions. A photovoltaic system including a solar panel, a fuzzy MPP tracker and a load (battery or resistance) is designed, simulated and constructed. Theoretical and experimental results are used to present the advantages of the proposed technique.
