Huang Jian-y · Chinese Journal of Power Sources · 2015
Power-over-Ethernet(Po E) is a kind of technology that offers DC power supply along with data transfers through existing Ethernet cabling. A 90 W high power Power-over-Ethernet system compatible with LTPo E++ and IEEE 802.3 standard was designed with the functions of automatic control and intelligent power management, could provide up to 90 W of power to the powered device(PD). The system's whole structure and the designing principle of the hardware were introduced, its working process was analyzed, finally the results of the experiments were given.
