Abstract
A multi-source power supply for supplying power that includes a first rectifier configured to convert a first AC power signal from a first source to a first DC power signal, a second rectifier configured to convert a second AC power signal from a second source to a second DC power signal and a common bus operatively connected to the first rectifier and the second rectifier and configured to combine a the DC power signals into a combined DC power signal, where the common bus distributes the combined DC power signal to at least one server.
Claims19
A server rack comprising:
- a plurality of servers each configured to receive DC power signals for powering one or more components of the corresponding server;
- and
- a multi-source power supply, comprising:
- a first rectifier configured to convert a first AC power signal from a first source to a first DC power signal;
- a second rectifier configured to convert a second AC power signal from a second source to a second DC power signal;
- and
- a common bus operatively coupled to the first rectifier and the second rectifier and configured to combine a plurality of DC power signals comprising the first DC power signal and the second DC power signal into a combined DC power signal, wherein the common bus distributes the combined DC power signal to the one or more servers to power one or more components of the corresponding server without input rectification by a server onboard power supply.
4 more elements
A system comprising:
- one or more server racks each comprising a plurality of blade servers;
- and
- a multi-source power supply coupled to the server rack, comprising:
- a first rectifier configured to convert a first AC power signal from a first source to a first DC power signal;
- a second rectifier configured to convert a second AC power signal from a second source to a second DC power signal;
- and
- a common bus operatively coupled to the first rectifier and the second rectifier and configured to combine a plurality of DC power signals comprising the first DC power signal and the second DC power signal into a combined DC power signal, wherein the common bus provides the combined DC power signal to one or more blade servers of the one or more server racks to power one or more components of the corresponding server.
4 more elements
A method comprising:
- receiving, at a multi-source power supply, a first AC power signal from a first source;
- rectifying, at the multi-source power supply, the first AC power signal to a first DC power signal;
- receiving, at the multi-source power supply, a second AC power signal from a second source;
- rectifying, at the multi-source power supply, the second AC power signal to a second DC power signal;
- and
- distributing, using a common bus of the multi-source power supply, coupled to the first rectifier and the second rectifier, a combined DC power signal to a plurality of blade servers to power one or more components of each blade server.
