In this paper, we present the development of an air-cooled 1MW bi-directional DC Solid State Circuit Breaker (SSCB) based on recently developed 91mm, 2.5kV Reverse Blocking-IGCT (RB-IGCT). The power electronic switch (RB-IGCT) has been designed and optimized to have very low conduction losses, less than 1kW at 1kA (on-state voltage drop <; 1V at 1kA, 400K) and high turn-off current capability (> 6.5kA at 1.6kV, 400K) which are the most important concerns of semiconductor based circuit breaker… CONTINUE READING
