Ageing Behaviours and Mechanisms of SiC MOSFET and Si IGBT in DC Solid‐State Circuit Breaker
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.We propose that this distributed thermal profile in IGBT mitigates localised stress. Conversely, the high concentration of thermal stress in SiC MOSFET's gate region leads to its severe ageing. ABSTRACT The rapid development of DC power systems in applications such as electric aircraft and microgrids has highlighted the need for high‐performance DC ...

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This study evaluates surge arrester performance in mitigating transient overvoltages during 400 kV transmission line switching in Iran, using EMTP‐RV software and statistical switching. Simulation results show that modelling corona effects reduces the surge arrester counter operation considerably, aligning with practical observations.
