Abstract

A novel system and methodology for controlling an output of Power Sourcing Equipment in a Power over Ethernet system based on a current limit threshold. The PSE has an auto-zero circuit for comparing a monitored output current of the PSE with the current limit threshold to control the output of the PSE.
