Abstract

Extension of zero voltage switching (ZVS) range of a Dual active bridge (DAB) converter is important especially at light loads. In this paper, the ZVS range of a DAB converter is increased by cascading a bidirectional buck-boost converter with a DAB converter. This proposed structure increases the maximum input and output currents, so output power can be controlled in a wider range. Simulation results confirm the performance of the proposed configuration.
