摘要： Power sourcing equipment comprising: a power input; an output port; a control circuit comprising a means for sensing that a voltage component of power received at the power input is above a pre-determined threshold; a non-uniform signal source; an impedance associated with the non-uniform signal source; and an electronically controlled switch responsive to the control circuit, the electronically controlled switch being arranged to switchably operatively connect the impedance to at least momentarily be seen across the output port; the control circuit being operative responsive to an output of the means for sensing to operatively connect the impedance via the operation of the electronically controlled switch; the electronically controlled switch being operative to disconnect the impedance from being seen across the output port in the absence of the indicative output.

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.
