| Abstract: | Power over Ethernet is one of the key technologies in EPA system. In this paper, the standard IEEE802.3af was briefly introduced, and the function demands and the collective design were described. Based on 12 C-BUS criterion, the authors adopted MSP430 MCU and TPS2383APSEPM to design PSE complying with IEEE802.3af standard. The methods of software design were emphasized in this thesis. Finally, an application example of this device used in EPA system was given, and it runs in high efficiency. |
