Uninterruptable power supply for device having power supply modules with internal automatic transfer switches

摘要

Techniques are described for determining whether power from a first power source is unavailable to a power supply module. In response to determining that power from the first power source is unavailable, the techniques de-couple the first power source from one or more components of an electronic device connected to an output of the power supply module with one or more de-coupling components of the power supply module that connect an automatic transfer switch (ATS) of the power supply module to an output of the power supply module. Subsequent to de-coupling the first power source from the one or more components of the electronic device, the techniques de-couple a power supply module from the first power source. The techniques couple the power supply module to a second power source for delivering power to the one or more components of the electronic device.

1. A method comprising:
determining, with a controller of a power supply module of an electronic device, whether power from a first power source is unavailable to the power supply module; responsive to determining that power from the first power source is unavailable, de-coupling, with one or more de-coupling components of the power supply module that connect an automatic transfer switch (ATS) of the power supply module to an output of the power supply module, the first power source from one or more components of the electronic device that are connected to the output of the power supply module; subsequent to de-coupling the first power source from the one or more components of the electronic device, de-coupling, with the ATS, the power supply module from the first power source; and coupling, with the ATS, the power supply module to a second power source for delivering power to the one or more components of the electronic device.
