Comparison of Thermal Stress During Short-Circuit in Different Types of 1.2-Kv SiC Transistors Based on Experiments and Simulations
Materials science forum(2017)
Abstract
The temperature evolution during a short-circuit in the die of three different Silicon Carbide1200-V power devices is presented. A transient thermal simulation was performed based on the reconstructedstructure of commercially available devices. The location of the hottest point in the device iscompared. Finally, the analysis supports the necessity to turn off short-circuit events rapidly in orderto protect the device after a fault.
