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).
