  • A New Nonisolated ZVS Bidirectional Converter with Minimum Auxiliary Elements

    DELSHAD Majid , VESALI Mahmood

    … <p>In this paper, a non-isolated bidirectional DC-DC converter with zero voltage switching and constant switching frequency is proposed. … Unlike the active clamp bidirectional converters, to create soft switching condition in both direction, only one auxiliary switch is used, which reduces conduction losses and the complexity of the circuit. …
