A 3 kW Bidirectional DC-DC Converter for Electric Vehicles Arsalan Ansari, Puyang Cheng and Hee-Jun Kim Dept. of Electronic Systems Engineering, Hanyang University,South Korea.
Abstract – A bidirectional DC-DC converter (BDC) is an indispensable electrical unit for the electric
vehicles (EVs). High efficiency, high power density, isolation, light weight and reliability are all
essential requirements for BDC. In this paper, a 3 kW BDC for the battery charger of EVs is proposed.
The proposed converter consists of a half-bridge structure on the primary side and an isolation
transformer and a synchronous rectifier structure on the secondary side. With this topology, minimum
number of switching devices are required for bidirectional power flow between the two dc buses of
EVs. The easy implementation of the synchronous rectification gives advantages in terms of
efficiency, cost and flexibility. The proposed BDC achieves high efficiency when operating in both
modes (step-up and step-down). A 3 kW prototype is implemented to verify theoretical analysis
and the performance of the proposed converter.
