METHODS AND SYSTEMS FOR SERVER POWER LINE COMMUNICATION

摘要

A server system includes a common power bus, a power supply to provide direct current (DC) power through the common power bus, at least one node including a processor to receive the DC power through the common power bus, a transmitter capacitive coupled to the common power bus to transmit a power information signal from the power supply through the common power bus, and at least one receiver capacitive coupled to the common power bus to receive the power information signal transmitted by the transmitter and to provide the received power information signal to the at least one node. A plurality of buffers respectively coupled between the common power bus and each of the power supply and the at least one node provide path separation for high frequency and low frequency currents.

主权项

1. A transmitter for communicating a power information signal through a power bus configured to provide power from a power supply unit to a node, the transmitter comprising:
a DC blocking capacitor coupled to the power bus; to reduce a size of a step-down transformer, circuitry to convert a first pulse having a first duration to a second pulse having a second duration, the second duration being less than the first duration; and the step-down transformer comprising: a primary winding to receive the second pulse; and a secondary winding coupled to the DC blocking capacitor to transmit the second pulse through the power bus.
