Analysis and Experiments for IGBT, IEGT, and IGCT in Hybrid DC Circuit Breaker

IEEE Transactions on Industrial Electronics, 2018
As power semiconductor devices are the key components of hybrid DC circuit breakers (HCBs), how to select suitable devices is critical for the whole HCB design. First, this paper compared the general characteristics of press pack insulated gate bipolar transistor (IGBT), injection-enhanced gate transistor (IEGT), and integrated gate commutated ...

A Multi-Functional Multi-Port Hybrid DC Circuit Breaker for Flexible DC Distribution Networks

IEEE Transactions on Power Delivery
To quickly clear short-circuit faults and avoid the threat to power electronic devices, a multi-functional multi-port DC circuit breaker (MP-DCCB) is proposed. The fault current is limited by line inductors and the fault current limiter (FCL).
