Dynamic Characterization Evaluation Tool Optimized for the Wolfspeed WolfPACK™ GM3 Half Bridge Module Platform

KIT-CRD-CIL12N-GMA

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 (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)
