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.

摘要： A power converter (14) can include a switching system (18) to convert a direct current (DC) input voltage to an output voltage based on a switching signal having a duty-cycle. A controller (16) can set the duty-cycle of the switching signal, depending on the DC input voltage, to one of a substantially constant value, such that the output voltage follows the DC input voltage in a normal mode, and a value that varies inversely with respect to the DC input voltage, such that the output voltage is substantially constant in another mode.

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： Apparatus and methods are provided. A system includes two or more power supplies receiving electrical energy from respective independent sources. One of the power supplies detects an anomalous condition of the associated energy source and provides an alert signal. At least one of the other power supplies transitions from a standby mode to a normal output mode in response to the alert signal. The failing power supply provides operating level energy to an electrical load while the one or more other power supplies transition from standby to normal output level.
