I'm looking at designing a high-current crowbar circuit. We need to blow a 1400A fuse on demand. One question that has arisen is, what about inductive kick? If you short a large capacitor through a fuse, like so:
the current in the fuse path may well reach 50kA before the fuse opens. That's a lot of energy built up in the inductance of the path between the cap and the fuse. So where does that energy go? Does it get burned off in the fuse as it opens? Or do you get an inductive kick on that node, potentially damaging anything else connected to it? Some of each?
