Application of CS-MCT in DC solid state circuit breaker (SSCB)

2018 IEEE 30th International Symposium on Power Semiconductor Devices and ICs (ISPSD), 2018
In this work, the application of cathode-short MOS-controlled thyristor (CS-MCT) in DC solid state circuit breakers (SSCB) is evaluated. Firstly, static and dynamic characteristics of CS-MCT are presented, and a low on-state resistance combined with a high surge current capability makes CS-MCT a promising candidate for SSCB.
