A discharging (Boost) mode of the bidirectional dc-dc converter with fuzzy logic controller is present in this paper .To achieve high voltage step-up conversion two boost conversion stages are obtained by controlling one power switch. High efficiency is achieved since the energy stored in the leakage inductor is recycled. For understanding the advantages of fuzzy logic control conventional PI control has applied and compared under the same circumstances of the converter. Simulation results show that fuzzy controlled converter has an improved steady state and transient performance than PI controlled converter. This converter can be used for Board Mounted Power supply (BMPS).
