Abstract
A power system which includes a battery (or string of batteries) as well as a preemptive fuse driver, PFD, system. The PFD protection system reliably protects circuits that could be damaged by long term fault currents. More specifically, the PFD protection system includes a sensor and a controller as well as a controlled switch. The controller includes a PFD control module which allows protection to be tuned specifically to the source and load characteristics.
