A novel hybrid DC circuit breaker for nodes in multi-terminal DC system

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
DC fault protection is one of the biggest challenge to multi-terminal direct current (MTDC) systems, because DC current has no natural zero crossing point. To overcome this problem, hybrid DC circuit breaker (DCCB), which serves as a promising solution to the isolation of DC faults, has been developed.

Combined Hybrid DC Circuit Breaker Capable of Controlling Current Flow

IEEE Transactions on Industrial Electronics, 2021
Two key challenges in meshed multi-terminal dc (MTdc) grids are line power flow management and fault current interruption, which can be solved by current flow controllers (CFCs) and hybrid dc circuit breakers (HCBs), respectively. However, the power losses and the implementation costs of CFCs and HCBs are relatively high.

Zero volt switching hybrid DC circuit breakers

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002
DC distribution networks have the advantage of easy connection of generators of different frequency, fuel cells, and storage devices like batteries and flywheels to a grid and the advantage of a lower current load of the cables. Despite these advantages, often an AC distribution network is chosen because of the lack of reliable DC switchgear.
