Advantages and challenges of using sic mosfets in a high power density insulated hv/lv dc/dc converter
Abstract
A safe connection of on-board automotive electric power grids is done by insulating HV/LV DC/DC con-verters. 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/dmĀ³ and power weight of ca. 3 kW/kg is presented which uses different suggested solutions to manage the named challenges when using SiC MOSFETs.
