The CRD3DD12P buck boost evaluation kit is optimized to demonstrate the high-speed switching capability of Wolfspeed’s 3rd Generation (C3M) silicon carbide (SiC) MOSFETs. The board features SMA connectors for monitoring the gate to source voltage. The SMA connectors offer much cleaner waveforms than traditional probes and ground leads.

This evaluation kit supports 4-lead and 3-lead TO-247 package MOSFETs as well as diodes in TO-247 and TO-220 packages. The kit contains everything needed including a heatsink, thermal interface, inductor, hardware, etc. as well as two Wolfspeed C3M MOSFETs to allow the user to begin testing within minutes of unpackaging the kit.

The kit can easily be run as a boost or as a buck converter. All of the supported topologies are listed below:

  • FULL BRIDGE (requires 2 kits)
