New Dynamic Characterization Tool for Wolfspeed’s WolfPACK™ SiC Power Modules
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™ 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 conjunction 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)
Optimized for Wolfspeed’s WolfPACK™ Silicon Carbide 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 6.2nH @ 10 MHz
On-board current viewing resistor (CVR)
Screw terminals for supply, midpoint and load inductor connections
