Claim Text:
1. A method comprising: receiving a source power supply at a first power supply unit configured to supply power to at least one electronic component, wherein the first power supply unit is one of a plurality of power supply units configured to supply power to the at least one electronic component in parallel by a power distribution bus; receiving, at a power supply controller coupled to the first power supply unit, a disable signal that indicates the first power supply unit should be disconnected such that the first power supply unit does not supply power to the at least one electronic component; disconnecting, in response to the disable signal, the first power supply unit from the source power supply such that the first power supply unit does not supply power to the at least one electronic component; and charging, in response to the disable signal, a bulk capacitance of the first power supply unit to a predetermined level while the first power supply unit is disconnected from the source power supply by delivering power from a second power supply unit of the plurality of power supply units to the bulk capacitance of the first power supply unit via the power distribution bus while the second power supply unit supplies power to the at least one electronic component.
