Operating DC Circuit Breakers With MMC [PDF]
IEEE Transactions on Power Delivery, 2018 High Voltage Direct Current (HVDC) grids may be protected from dc faults through the application of HVDC circuit breakers. Recent advances in dc circuit breaker technologies may allow faults in the dc grid to be cleared without a permanent loss of power to the connected ac grids.

Interlink Hybrid DC Circuit Breaker [PDF]
IEEE Transactions on Industrial Electronics, 2018 —To protect HVDC grids from DC faults, the concept of a hybrid DC circuit breaker is widely accepted due to its low conduction losses and fast interruption speed. For a well-built DC grid, a massive number of hybrid DC circuit breakers have to be installed. This will lead to high capital costs.

A Dual-Bridge Hybrid DC Circuit Breaker [PDF]
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021 Various DC circuit breakers (DCCBs) have been widely proposed for the DC fault protection of high-voltage direct-current (HVDC) grids. In recent years, hybrid DCCBs (HCBs) have been paid significant attentions due to their features of low power losses and fast dynamic response.

Arc motion and gas flow in current limiting circuit breakers operating with a low contact switching velocity [PDF]
, 2002 Arc motion in low voltage (240 VAC) high current (10/sup 3/-10/sup 4/A.) current limiting-circuit breakers is dominated by arc root mobility. The mobility is influenced by the gas flow and gas composition in the contact region, but there is little ...
