Abstract
A power distribution system for a data center includes a transformer that transforms three-phase source power to three-phase operating power. The phase-to-neutral operating voltage for each phase is at least about 260 volts. Power distribution units are coupled to the transformer. The power distribution units supply operating power from the transformer to computer systems in the data center.
Claims20
A power distribution system for computer systems in a computer room of a data center, comprising:
- one or more transformers configured to step down a three-phase source power to a three-phase operating power;
- and
- one or more power distribution units configured to receive at least one phase of the three-phase operating power from at least one of the one or more transformers and distribute the at least one phase of the three-phase operating power to individual ones of a plurality of computer system power supplies at an operating voltage of at least about 260 volts.
A data center, comprising:
- one or more computer systems that individually include at least one power supply configured to operate at an operating voltage of at least about 260 volts;
- a first transformer configured to step down a three-phase source power to a three-phase intermediate power that has a lower voltage than the three-phase source power;
- a second transformer configured to step down the three-phase intermediate power to a three-phase operating power that has a lower voltage than the three-phase intermediate power;
- and
- one or more power distribution units configured to distribute at least one phase of the three-phase operating power to the at least one power supply at the operating voltage of at least about 260 volts.

A method of supplying power to computer systems in a computer room of a data center, comprising:
- stepping down, via a first transformer of a power distribution system of the data center, a three-phase source power from a source power feed to a three-phase intermediate power;
- stepping down, via a second transformer of the power distribution system of the data center, the three-phase intermediate power to a three-phase operating power;
- and
- distributing, via one or more power distribution units in the computer room, at least one phase of the three-phase operating power to individual ones of a plurality of power supplies at an operating voltage of at least about 260 volts.
