    摘要： Novel techniques for balancing power or current drawn from multiple power supply inputs by controlling switching circuits associated with the respective power supply inputs. Each switching circuit may be controlled so as to limit current in its transformer or inductor in each switching cycle to a peak or average current value common to all switching circuits.

    摘要： A novel system and methodology for supplying power over a communication cable, such as an Ethernet cable, using power distribution circuitry for controlling power distribution between wires or pairs of wires in the communication cable. The power distribution circuitry may control distribution of current among wires or pairs of wires in the communication cable. In particular, balance of current among the wires or pairs of wires may be provided.

    摘要： System and methodology for managing power supplied to powered devices over communication links, such as Ethernet links. A power supply system has multiple power supply ports for providing power to respective powered devices via multiple communication links. A power-in-use bus shared by the multiple power supply ports is configured for receiving a power-in-use signal representing total amount of power being used by the powered devices. Multiple port control circuits associated with the power supply ports are responsive to the power-in-use signal for controlling supply of power to the respective powered devices.
