摘要： A redundant AC-DC power supply system and method is disclosed. A first AC-DC power converter is configured to generate a first output voltage and a first relay is configured to selectively couple and decouple the first AC-DC power converter to an output of an output circuit. A second AC-DC power converter is configured to generate a second output voltage. A second relay is configured to selectively couple and decouple the second AC-DC power converter to the output. A controller is configured to operate the first and second AC-DC power converters and the first and second relays to provide redundant sources of power for the output and to mitigate circulating current flow between the first and second AC-DC power converters.

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.
