Optimization of the Magnetic, Fast and Controllable Commutation Switch for Hybrid DC Circuit Breaker

2025 5th International Conference on Electrical Machines and Drives (ICEMD)
A hybrid DC circuit breaker (HDCCB) as the applicable protection tool employs a load commutation switch (LCS) for commutation of the fault current from the path, including a mechanical switch to the interruption branch.

Enhanced Current Commutation Drive Circuit for Hybrid DC Circuit Breaker

2025 33rd International Conference on Electrical Engineering (ICEE)
Among hybrid DC circuit breakers (HDCCB) structures, the current commutation drive circuit (CCDC) structure has received more attention due to its low pre-fault losses. The CCDC has two coils with magnetic coupling.
