Abstract
A redundant power system that includes switch array and component failure detection circuitry is disclosed. The redundant power system includes a plurality of available AC power lines, one of which is coupled to a load through the switch array. A controller instructs the switch array to couple an available AC power line to the load, based upon status information received about the condition of a particular AC power line. Each switch within the switch array includes detection circuitry to determine if the switch has failed, for example, in a stuck closed position.
