 Abstract   The paper presents the design, and demonstration of a high efficiency 20 kW SiC based isolated dc-dcconverter for battery charger application that can be used for fast charging or vehicle to grid charging.The paper discusses the design considerations and analysis of various losses in the converter. The dc-dcconverter has an input voltage of 700V and the output is connected to a 700V battery bank. The dc-dcconverter uses 1200V SiC MOSFET at the primary side and 1200V SiC diodes at the secondary side ofthe converter. The hardware prototype of the converter is developed and the efficiency of the converteris measured. The proposed converter has achieved a maximum measured conversion efficiency of97.8\%, 98.7\% and 98.9\%, at output voltages of 350 V, 560V and 686V respectively.
