Dynamic Characterization Evaluation Tool Optimized for the Wolfspeed 2300 V WolfPACK™ GM Half Bridge Module Platform

Wolfspeed’s KIT-CRD-CIL23N-GMA is a dynamic characterization tool that can be used to evaluate and optimize switching performance of Wolfspeed’s 2300 V WolfPACK™ GM 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 board options allows measurement of:

• Timing (T_Delay-On; T_Delay-Off; T_Rise; T_Fall)
• Overshoot (V_DS-Max; I_D-Max)
• Speed (di/dt; dv/dt)
• Switching Loss (E_ON; E_OFF; E_RR)

Specifications

• Optimized for Wolfspeed’s 2300 V WolfPack™ GM Silicon Carbide half bridge power modules
• On Board 120uF Bulk Capacitance and High Frequency Film Capacitor Bank
• High speed; low inductance layout with stray inductance of 7 nH at 10 MHz
• On-board Current Viewing Resistor (CVR)
• Screw terminals for power supply and load inductor connections
