Abstract

Current-Fed Dual Active Bridge (CFDAB) is an isolated DC/DC converter with bidirectional power flow, which has been widely used in the energy storage systems recently. The two main losses of the converter are switching losses of the power switches and transformers losses. This paper proposes a method to improve the efficiency of the CFDAB converter by employing new SiC MOSFET technology instead of the traditional Si MOSFET, in combination with zero voltage switching technique. In addition, Litz wire is also adopted to reduce the losses on the high frequency isolation transformer. The feasibility and effectiveness of the proposed solution is verified by both numerical simulations and experiments with a prototype 2.5kW converter.
