Latest electric car architectures are operating with 800 V batteries and 48 V power grids. Hence, compact 800 V/48 V DC/DC converters are necessary. Within the following paper advantages and challenges of using SiC MOSFETs in such applications are discussed. A developed compact prototype with maximum power density of ca. 8 kW/dm³ and power weight of ca. 3 kW/kg is presented which uses different suggested solutions to manage the named challenges when using SiC MOSFETs.enDC-DC convertersEnergy managementHVDC power transmissionIntelligent robotsMOSFET devicesPower electronicsSiliconSilicon carbideSilicon compoundsVehicle-to-gridElectric carsElectric power gridsHigh power densityMaximum power densityPower gridsSiC MOSFETsElectric power transmission networks670620530conference paper
