Abstract: A power supply system may comprise a plurality of input buses and an output bus. A plurality of multi-input power supplies may be disposed between the plurality of input buses and the output bus. The plurality of multi-input power supplies may be configured to supply a predetermined amount of power to the output bus before and after a failure event. The failure event may comprise at least one of the following: a failure of a one of the plurality of multi-input power supplies and loss of power on one of the plurality of input buses. Each input to the power supply may include an independent power section to support near or full output power in the event of another input power loss. Any input line loss from an independent power bus/grid may provide line redundancy to the power supply and to the power system as an Uninterruptable Power Supply.
