1. A method comprising:
transmitting multi-phase pulse power from power sourcing equipment to a powered device, 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 power states and high direct current power states, wherein each of said multiple phases carries a portion of a load current to the powered device; and
synchronizing the pulses at the power sourcing equipment with pulses at the powered device.
