Abstract: In this paper fuzzy logic controller (FLC) based maximum power point tracking (MPPT) for a three-port bidirectional isolated dc-dc converter proposed for power management to photovoltaic-Battery sources. This converter has a benefit of using smallest amount of switches which reduces the switching losses. The inductor-capacitor-inductor (LCL) resonant circuit realized to achieve soft switching. The converter is modelled to instantaneous power management of photovoltaic (PV) panel, battery and load. The proposed MPPT based on FLC is capable of attaining maximum power from PV panel when solar radiation available. The charging and discharging controller of the battery works when the extra energy and power deficiency with respect to the load, respectively. The presentation of fuzzy logic with numerous membership function (MF) is analyzed to develop the MPPT. Simulation results shows that performance of FLC based MPPT is better than conservative perturb and observe (P&O) MPPT.
