A Series-Type Hybrid Circuit Breaker Concept for Ultrafast DC Fault Protection
IEEE transactions on power electronics, 2022 A new series-type hybrid circuit breaker (S-HCB) concept for dc fault protection is reported that is fundamentally different from other prior-art hybrid circuit breakers (HCB) or solid-state circuit breakers (SSCB) in the literature.

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).

A hybrid circuit breaker with fault current limiter circuit in a VSC-HVDC application
Protection and Control of Modern Power Systems, 2022 A conventional hybrid circuit breaker (HCB) is used to protect a voltage source converter-based high voltage direct current transmission system (VSC-HVDC) from a short circuit fault. With the increased converter capacity, the DC protection equipment also
