How to Make a PoE PD System More Efficient by Using a Flyback Converter
PoE sends power over the Ethernet cable by injecting 50 V DC into the center taps of the Ethernet transformers. Power is sent via two or four twisted pairs of cables. One of the key aspects of the IEEE standard is that it allows power to be injected from the Ethernet switch to both positive
