Wolfspeed's SiC 20 kW LLC Reference Design

Categories // Latest News Power

The CRD-20DD09P-2 makes it easy to evaluate converter level efficiency and power density gains when using Wolfspeed’s new 1000 V, 65 mΩ SiC MOSFETs in a 4L-TO247 package in a full bridge resonant LLC circuit.

It also can be used to evaluate the integration of a SiC-based isolated DC/DC stage in a larger multi-stage prototype system, like a fast DC charger for electric vehicles.
