Description
Technical Field

Currently, Power Over Ethernet (POE) is a local area network technology that can provide dc Power to a Power Device (PD) through a twisted pair cable. The standard adopted by POE in the industry is IEEE 802.3af, which specifies that a power sourcing equipment can supply power to a powered device with power below 13W over ethernet. In order to adapt to high-power applications, IEEE began to develop a new POE standard 802.3at (POE plus) in 2005 to improve the power that POE can transmit, wherein the reverse power supply function is to meet the reverse power supply requirement (i.e. 10W @250 m) when a single port of a Distributed Processing Unit (DPU) normally works at a minimum distance of 250 m, and the diameter of an ethernet wire used is 0.4-0.6 mm. Specifically, the implementation on the device refers to that the device is used as a PD device, and the PD device is used in cooperation with a Power Source Equipment (PSE) device to perform a remote reverse Power supply function, so as to provide a Power supply required by the device.
In the prior art, reverse power supply has two modes, the first mode is a fair power supply mode, that is, each path of user supplies power to a PD through a PSE, and when a single path of user supplies power, only the path of user service port is opened; when multiple paths of users supply power, only the service port of the power supply user is opened, and the power supply current of each path of users is equalized.
