Abstract
An active/passive fuse module including a base, a busbar disposed on the base and including a fuse element extending over a cavity in a top surface of the base and having a plurality of weak points formed therein, a pyrotechnic interrupter (PI) disposed atop the base and including a piston disposed within a shaft above the fuse element, the piston having an edge with a geometry that corresponds to a geometry of a pattern defined by the weak points in the fuse element, a first pyrotechnic ignitor coupled to a controller and configured to detonate and force the piston through the fuse element upon receiving an initiation signal from the controller, and a second pyrotechnic ignitor coupled to the busbar by a pair of leads and configured to detonate and force the piston through the fuse element upon an increase in voltage across the leads.
