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.

Analysis and simulation of the proactive hybrid circuit breaker

2015 IEEE 11th International Conference on Power Electronics and Drive Systems, 2015
High Voltage Direct Current (HVDC) short circuitprotection is a fundamental requirement for any HVDCtransmission system. Presently, all point-to-point links areprotected using circuit breakers on the AC side of theconverters. In order to enable HVDC grids, a more advancedprotection system must be developed. HVDC circuit breakersare one solution for the
