摘要： Plural electric power supplies are connected in parallel to an output bus. The plural supplies include a primary power supply and a redundant switching power supply. The primary power supply is configured to provide output current to a load when the primary power supply is operating normally. The redundant supply is configured to remain online while not providing output current to the load when the primary power supply is operating normally, but to begin providing output current to the load when the primary power supply is not operating normally.

摘要： A redundant power supply method is provided. The method includes communicatively coupling a load to a first source via a plurality of first power supplies and to a second source via a plurality of second power supplies. The method further includes bi-directionally communicatively coupling a controller to the plurality of first power supplies and to the plurality of second power supplies. The method includes activating a first portion of the plurality of first power supplies to supply power to the load, wherein the controller determines the number (“N”) of first power supplies activated, and activating at least one of the plurality of second power supplies to supply power to the load. The method also includes monitoring for at least one fault condition in each of the active first power supplies and in each of the active second power supplies.

摘要： A switching power supply includes power factor correction circuitry and a standby output converter. One or more loads may be coupled to one or more outputs of the switching power supply. The switching power supply is configured to disable the power factor correction circuitry under some load conditions and to enable the power factor correction circuitry under other load conditions. As a consequence, power that would have been drawn by the power factor correction circuitry is conserved when the power factor correction circuitry is disabled.
