Abstract :
This paper deals with the current interruption properties of self-recovering micro fuse (SRF) by applying a pulse-shaped overcurrent. The current interruption operation, i.e. the OFF state transition by flowing overcurrent, is one of the most important operations for SRF device, along with the self-recovering operation and the mechanical fuse operation as a additional function. Consequently, we successfully achieved the current interruption operation of SRF device under pulse-shaped current, and investigated fundamental interruption properties such as breaking current and breaking time. Also, we discussed the interruption mechanism in view of heat generation and electromagnetic force.
