Abstract
A semi-active bridge for furnishing voltage of a correct polarity to a powered device in a Power over Ethernet (PoE) network is disclosed. In one or more implementations, the semi-active bridge includes a diode having an anode portion and a cathode portion. The anode portion of the diode is connected to an input terminal, and the cathode portion of the diode is connected to an output terminal. The semi-active bridge also includes an active transistor device having a source region and a drain region. The drain region of the active transistor device is connected to the input terminal, and the source region of the active transistor device is connected to the output terminal.
