摘要： A method for preventing an excess voltage from appearing at an output of a power over Ethernet controller, the method comprising: sensing that a powered device has been disconnected from a port; enabling a bypass path around a means for unidirectional current flow operatively connected to the port; and disconnecting power to the port responsive to the sensed disconnect, whereby the bypass path enables a discharge path for an output capacitor present across the port. The invention also provides for a circuit having a bypass path around a means for unidirectional current flow, the bypass path being enabled by a control circuit to prevent an excess voltage from appearing at a sensing input of the control circuit. In an exemplary embodiment the bypass path is enabled approximately simultaneously with disconnecting power from the output port.

摘要： Power distribution apparatus, for controlling supply of a current from an electrical power source to at least one load, includes a current sensor, which is coupled to provide an indication of a magnitude of the current flowing to the at least one load. A current limiter is adapted, responsive to the indication, to apply a pulse width modulation to the current drawn from the source so as to maintain the magnitude of the current flowing to the at least one load within a predetermined limit.

摘要： A system and method for enabling power applications over a single communication wire pair. In one embodiment, a data transformer is provided that has three separate windings. Two of the windings are tied to each other via high frequency pass DC-blocking capacitors, or another suitable element that creates an AC path while providing a DC block, such that the voltage forms on either ends of the DC-blocking capacitors and the signal is sent on the outer legs of each winding. A circuit measures the current draw (I) and injects a current proportional to, but smaller than, I into a third bias cancellation winding.
