Abstract
Disclosed herein is a current circuit breaker that protects a semiconductor module by using fast switches to block a current. The current circuit breaker includes: a first switch configured to be opened upon a fault current being generated; a second switch connected to the first switch and configured to be opened after a predetermined period of time elapses since the first switch has been opened; a semiconductor module having an end connected to the first switch and another end connected to the second switch; a capacitor having a terminal connected to the second switch and the other terminal connected to the semiconductor module; and a surge arrester connected across the capacitor and configured to change its resistance according to a voltage across the capacitor to block the fault current.
