Intended to speed the transition from silicon to silicon carbide (SiC), Wolfspeed's SpeedVal Kit is a versatile modular evaluation platform that provides a flexible set of building blocks for in-circuit evaluation. Enabling the quick evaluation and optimization of the high-speed dynamic switching performance of Wolfspeed SiC MOSFETs, the platform can pair with a variety of gate-driver options from company partners, as well as perform high-power thermal testing.
To complement hardware testing, a modular Spice model was developed for each block in the system. In addition, a novel card-edge connection to the power daughtercard enables users to change SiC devices quickly while maintaining a low-inductance connection to the dc bus. This approach lets the same platform evaluate SiC devices in a range of packages from surface-mount TOLL devices up through TO-247 packages.
