Reliability design of 10 kV SiC-MOSFET power modules based on thermo-mechanical simulations

In this PhD thesis, the thermo-mechanical reliability performance of 10 kV SiC-MOSFET power modules, which is a promising power electronics for medium voltage applications, is evaluated for power cycling and thermal cycling tests using 3D thermo-mechanical simulation.Then, the thermo-mechanical characteristics of them are clarified and a digital design method to improve the thermo-mechanical reliability is proposed using 3D modeling.
