| Abstract |
Advanced high voltage (3.3-15kV) SiC MOSFETs have been developed for future medium voltage converters over the past decade due to their superior performance. In order to better understand the operation limits and potential of these devices, this paper evaluates the Imax-fsw-dv/dt trade-off (maximal current-handling capability at a specific switching frequency and at a defined switching speed) for high voltage SiC MOSFETs based on a proposed linearized analytical switching loss model. There, high voltage SiC MOSFETs manufactured by Cree combined with data from literature for scaling are used as reference. |
