Abstract
Provided is a fault current limiter, the limiter including a detector detecting an inflow of a fault current and transmitting a turn-on signal to a first switch and transmitting a turn-off signal to a power semiconductor element, the power semiconductor element changed to an OFF state by the turn-off signal, the first switch forming a current limiting circuit by being switched to an ON state by the turn-on signal, and a resistance element blocking the fault current, wherein the series connection between the resistance element and the first switch is connected in parallel to the power semiconductor element.
