Abstract
In a powered device (PD), four MOSFETs are used in a rectifier circuit. The four MOSFETs are disposed based on a premise that an electric potential of a contact pair 1-2 is lower than that of a contact pair 3-6 and an electric potential of a contact pair 7-8 is lower than that of a contact pair 4-5, so that a PoE current of each contact group passes through only two of the MOSFETs but does not pass through a diode.
