In this paper a 5kW step-down converter for low-voltage high-current application is presented using normally-off SiC JFETs as high voltage power switches, operating with efficiency close to 98%. Different low voltage side rectification solutions and loss estimations are also presented. As results show higher power density and efficiency can be achieved in medium- or high-power DC-DC applications by replacing silicone power devices with SiC alternatives.
