Abstract
In some examples, a power adapter for sharing redundant power comprises a primary power input; a redundant power input; a redundant power supply identification signal (RPS ID) input; and a controller coupled to the RPS ID input. The controller is to direct power from the primary power input to an electronic device; direct power from the redundant power input to the electronic device, to another power adapter, or both; modify an RPS ID from the RPS ID input in response to directing power from the redundant power input to the electronic device; and output the modified RPS ID to the another power adapter.
Claims13
A first power adapter for sharing redundant power, comprising:
- a primary power input;
- a redundant power input;
- a redundant power supply identification signal (RPS ID) input;
- and
- a controller coupled to the RPS ID input, the controller to:
- direct power from a primary power supply through the primary power input to an electronic device;
- direct power from a redundant power supply through the redundant power input to the electronic device, to a second power adapter, or both;
- modify a first RPS ID from the RPS ID input to a second RPS ID in response to directing power from the redundant power supply through the redundant power input to the electronic device, the first RPS ID indicating a first available power budget of the redundant power supply;
- output the second RPS ID to the second power adapter;
- and
- receive a third RPS ID from the second power adapter,
- wherein the second RPS ID indicates a second available power budget of the redundant power supply and the third RPS ID indicates a third available power budget of the redundant power supply, wherein the second available power budget differs from the third available power budget.
A system for sharing redundant power, comprising:
- a first buck-boost converter coupled to a primary power input and to a power output;
- a first diode positioned between the first buck-boost converter and the power output
- a second buck-boost converter coupled to a redundant power input and to the power output;
- a second diode positioned between the second buck-boost converter and the power output;
- a redundant power output coupled to the redundant power input;
- and
- a controller coupled to a redundant power supply identification signal (RPS ID) input, to an RPS ID output, to an enable input of the first buck-boost converter, and to an enable input of the second buck-boost converter.
A system for sharing redundant power, comprising:
- a first electronic device;
- a first power adapter coupled to the first electronic device;
- a first primary power supply coupled to the first power adapter;
- a second electronic device;
- a second power adapter coupled to the second electronic device;
- a second primary power supply coupled to the second power adapter;
- and
- a redundant power supply coupled to the first power adapter via a first power supply connection and a first redundant power supply identification signal (RPS ID) connection, the first power adapter coupled to the second power adapter via a second power supply connection and a second RPS ID connection,
- wherein the first power adapter to:
- update a first RPS ID received from the first RPS ID connection to a second RPS ID based on power consumption by the first electronic device;
- and
- output the second RPS ID to the second power adapter, and
- wherein the first RPS ID indicates a first available power budget of the redundant power supply and the second RPS ID indicates a second available power budget of the redundant power supply.
