Abstract
In one embodiment, a method includes transmitting multi-phase pulse power from power sourcing equipment to a powered device in a data center, wherein the multi-phase pulse power comprises multiple phases of power delivered in a sequence of pulses defined by alternating low direct current voltage states and high direct current voltage states, and synchronizing the pulses at the power sourcing equipment with the pulses at the powered device.
Claims31
A method comprising:
- transmitting multi-phase pulse power from power sourcing equipment to a powered device in a data center, wherein transmitting the multi-phase pulse power comprises transmitting, by the power sourcing equipment, multiple phases of power in a sequence of pulses defined by alternating low direct current voltage states and high direct current voltage states;
- and
- synchronizing the pulses at the power sourcing equipment with pulses at the powered device.
A method comprising:
- receiving multi-phase pulse power at a powered device installed in a rack in a data center environment, wherein the multi-phase pulse power comprises multiple phases of power transmitted by power sourcing equipment in a sequence of pulses defined by alternating low direct current voltage states and high direct current voltage states;
- and
- transmitting said multi-phase pulse power to a plurality of loads at the powered device.
A power distribution system comprising:
- power sourcing equipment for transmitting multi-phase pulse power, wherein the multi-phase pulse power comprises multiple phases of power transmitted in a sequence of pulses defined by alternating low direct current voltage states and high direct current voltage states;
- a powered device for receiving said multi-phase pulse power;
- and
- a cable for transmitting said multi-phase pulse power from the power sourcing equipment to the powered device over a distance less than fifty meters.
A method comprising:
- transmitting pulse power from power sourcing equipment to a powered device in a data center, wherein the pulse power is transmitted in a sequence of pulses defined by alternating low direct current voltage states and high direct current voltage states;
- and
- synchronizing the pulses at the power sourcing equipment with pulses at the powered device;
- wherein said synchronizing the pulses at the power sourcing equipment with the pulses at the powered device comprises transmitting a synchronization signal out of band from the pulse power.
