Abstract: This application discloses an energy-saving power sourcing method. Power sourcing equipment receives an input voltage of a powered device fed back by the powered device, and adjusts, based on the input voltage, a power sourcing voltage that is output to the powered device, so that the input voltage of the powered device is a maximum voltage, thereby reducing a link loss and saving electric power resources of the power sourcing equipment.

Abstract: A filtering-based power supply apparatus used in a power sourcing equipment (PSE) includes a power supply control circuit and an adaptive filter circuit. The power supply control circuit includes a power supply channel and a detection module. The power supply channel includes a control switch configured to control on and off of the power supply channel. The detection module is configured to send a detection signal to the power supply channel to detect whether a peer device connected to the power supply channel is a valid powered device. The control switch is turned off in a detection process of the power supply channel. The adaptive filter circuit is configured to filter noise in the detection signal in the detection process of the power supply channel.

Abstract: Power sourcing equipment for power over Ethernet (PoE) includes a power supply control circuit, an Ethernet port, and a surge protection circuit. The surge protection circuit includes a first circuit, a second circuit, and a common discharge circuit. The first circuit is connected to a power supply pin group of the Ethernet port, the power supply control circuit, and the common discharge circuit. The second circuit is connected to a non-power supply pin group of the Ethernet port and the common discharge circuit. The first circuit transmits, to the common discharge circuit, a first surge that is input from the power supply pin group. The second circuit transmits, to the common discharge circuit, a second surge that is input from the non-power supply pin group. The common discharge circuit discharges the first surge and the second surge to ground.
