A voltage-clamped bidirectional fault current limiter based on a three-winding coupled inductor for DC power grids

International Journal of Electrical Power & Energy Systems
The DC fault is a serious challenge to voltage-source-converter-based HVDC (VSC-HVDC) systems, and the fault current limiter (FCL) is one of the key measures to solve the DC fault and reduce the capacity of the DC circuit breaker.
