This paper presents a high efficiency converter with input power source from a low voltage, high current DC source solar PV system. Therefore, it is desirable to create a power converter with a topology suited to the attributes. This converter has a coupled inductor with high transformation ratio and a voltage multiplier is adapted to step-up the input voltage with high conversion ratio. In step up mode, the primary and secondary windings of the coupled inductor are operated in parallel for charging and series for discharging to achieve high step up voltage gain. It is also proposed fuzzy logic controller (FLC) for significantly improving the performance of DC-DC converter, FLC improves the efficiency of converter by control the output voltage.
