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.

A Study of Synchronous Rectifier for High Efficiency Multi Output DC-DC Converter Hyun Jeon Department of Electronic Engineering The Graduate School of Cheongju University. Supervised by Professor Tae-Young Ahn, Ph. D 

ABSTRACT
 This paper proposed synchronous rectifier in forward converter including resonance reset did not get efficiency drive waveform for that is existent dead time period. Therefore, proposed synchronous rectifier of new way accordingly to solve problem by happened drive circuit. Confirmed usefulness and practicality by drive circuit that compose experiment circuit and propose through experiment result. Input voltage of experiment circuit are 380V, and output voltage are 12V, and maximum output current is 20A, and maximum output was 100W. And, to report the experimental results the core losses of VRM inductor. The VRM, that has a output voltage 1.5V, output current 60A, maximum power of 90W. Experimental results verify, the VRM has a almost same data of fast transient response, a efficiency test with high flux and ferrite inductor. A maximum power conversion efficiency of the experimental VRM was measured at 92% within 0.2% load regulation.
