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.

Hybrid HVDC circuit breaker with self‐powered gate drives [PDF]

IET Power Electronics, 2016
The ever increasing electric power demand and the advent of renewable energy sources have revived the interest in high‐voltage direct current (HVDC) multi‐terminal networks. However, the absence of a suitable circuit breaker (CB) or fault tolerant voltage source converter station topologies with the required characteristics (such as operating speed ...

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.

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).
