Cryogenic DC Circuit Breaker Based on High‐Power Press‐Pack IGBT

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This paper presents the performance of cryogenically compatible 3.3 kV/1.5 kA PP‐IGBTs as the main circuit breaker in a hybrid circuit breaker. The 3.3 kV/1.5 kA press‐pack IGBT can interrupt currents exceeding 5.1 kA when immersed in a liquid nitrogen bath. PP‐IGBTs are promising candidates for high‐power circuit breakers in cryogenically cooled power

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 ...
