DC vacuum circuit-breaker

2008 23rd International Symposium on Discharges and Electrical Insulation in Vacuum, 2008
The results of switching tests of a DC vacuum circuit-breaker designed for rated voltage 3.3 kV and rated current 3000A are presented. The circuit-breaker is intended for current interruption in the networks with fault currents up to 30 kA. To interrupt the direct current, the authors used a method of artificial current transition through zero in the ...

Design and Simulation of a Bidirectional DC Circuit Breaker

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
In recent years, DC microgrid has been developing continuously and its application range is more and more wide, which puts forward higher requirements for its protection. This paper proposes a bidirectional DC solid-state circuit breaker (SSCB), which allows power to flow bidirectionally and can be used in bidirectional DC microgrid protection ...

A New Z-Source DC Circuit Breaker

IEEE Transactions on Power Electronics, 2010
A novel type of circuit breaker is introduced for operation at medium-voltage dc with future naval ship power systems as a targeted application. The breaker utilizes a z-source LC circuit in order to automatically commutate a main-path SCR during a fault.
