Bridge-Type Integrated Hybrid DC Circuit Breakers [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 The inclusion of a large number of controllable semiconductor devices in conventional hybrid dc circuit breakers (HCBs) may significantly increase the cost of an HVdc grid protection scheme. In an attempt to reduce this cost, this paper proposes the use of two novel topologies of bridge-type integrated HCBs (BT-ICBs).

Superconducting Interface for a DC Circuit Breaker [PDF]
8th IET International Conference on Power Electronics, Machines and Drives (PEMD 2016), 2016 High voltage direct current (HVDC) circuit breakers are a key technology to enable fault management for multi terminal DC (MTDC) networks. DC circuit breakers using superconductors for current limiting have been proposed previously and experimentally tested at low voltage levels.
