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.
