Abstract
A fault recovery method for multi-phase power converters enables delivery of reduced output power of as much as 66% of normal power in the event of a shorted power switch component. The need for redundant power converters in conventional multi-phase space power systems is reduced, if not eliminated. Fault recovery includes 1) detecting a shorted power switch fault; 2) providing short circuit current protection; 3) providing isolation of the shorted power switch; and 4) reconfiguring the remaining undamaged power switches.
