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

open access: yesIET 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
