Buck Boost Evaluation Board for 650 V Silicon Carbide C3M™ MOSFET in a TO-247-X Package

Product shot of Wolfspeed's KIT-CRD-3DD065P Evaluation Board.
KIT-CRD-3DD065P

This evaluation board demonstrates the switching and thermal performance of 650 V 60 mΩ Silicon Carbide (SiC) C3M™ MOSFET in a TO-247-4 package configured in a half bridge topology. The board is designed for characterizing EON and EOFF losses and steady state thermal performance in Silicon Carbide MOSFETs. The board can be configured to run as a buck or boost converter in either synchronous or asynchronous modes. The PCB also supports replacing the SiC MOSFETs with TO-247-3 package components to allow for evaluation of either package. A full LTSpice model including parasitic elements that nearly matches the performance of the hardware is available for download.

This design allows measurement of:

  • Timing (TDelay-On; TDelay-Off; TRise; TFall)
  • Overshoot (VDS-Max; ID-Max)
  • Speed (di/dt; dv/dt)
  • Switching Loss (EON; EOFF; ERR)
  • Efficiency during operation up to 2.5kW

Specifications

  • Max DC Input / Output Voltage of 450V
  • Max Power of 2.5kW @ 100kHz (limited by on-board inductor; higher levels possible with alternate inductor)
  • Compatible with TO-247-4 and TO-247-3 SiC MOSFETs;
  • Compatible with TO-247 and TO-220 SiC Schottky diodes
  • Dedicated gate drivers and isolated power supplies for each C3M SiC MOSFET
  • Optimized locations for scope probe measurements of drain current; VGS; and VDS and IS
  • Synchronous and asynchronous buck and boost topologies supported
  • Kit includes two SMA to BNC adapters for measuring VGS waveforms
  • Includes heatsink; thermal clips and isolated thermal pads
