Abstract: A power distribution system in operative association with a source and a plurality of loads includes a converter, a power distribution unit including a plurality of solid state power controllers and configured to provide power from converter to plurality of loads, and a fault protection unit operatively coupled to converter, power distribution unit, or both. The fault protection unit includes a sensor configured to sense current at output terminal of at least one of power distribution unit and converter and a controller configured to compare sensed current with a corresponding threshold value of current, identify presence of a fault in at least one of plurality of loads, power distribution unit, and converter based on comparison, and activate a desired protection scheme to provide fault ride through during the presence of the fault.
