摘要
介绍了以太网供电系统的构成及以太网供电过程,提出了一款用电设备电源适配器设计方案。该方案在无需大量更换现有设备的情况下,能低成本地解决低功率以太网设备的电源布线问题。
The structure of power over EtherNet technology system and power supply process of power over EtherNet were introduced.It also presented a new design scheme of powered device power adapter.The new proposal pays low cost on solving the power supply problems of power sourcing equipment without replacing a large number of existing equipment.
