Request Sample
Wolfspeed’s KIT-CRD-CIL12N-GMA is a dynamic characterization tool that can be used to evaluate and optimize switching performance of Wolfspeed’s WolfPACK™ GM3 Silicon Carbide (SiC) half-bridge power modules. A clamped inductive load (CIL) test circuit with current measurement provides a high speed; low inductance test fixture for double pulse testing. This test fixture in conjuction with a choice of gate driver boards options 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)

Specifications

  • Optimized for Wolfspeed’s WolfPack GM3 SiC half bridge power modules
  • DC bus voltage up to 1000V
  • On Board 200uF Bulk Capacitor and High Frequency Film Capacitor Bank
  • High speed; low inductance layout with stray inductance of 4.9nH @10Mhz
  • On-board Current Viewing Resistor (CVR)
  • Screw terminal‘s for supply; midpoint and load inductor connections
