Abstract
An apparatus includes a signal generator and a control circuit. The signal generator includes a control terminal and includes a current electrode coupled to a terminal that is configured to couple to a power line to receive direct current (DC) power from a power generator. The control circuit is coupled to the current electrode and the control terminal of the signal generator. The control circuit determines an impedance associated with the power generator and applies a control signal to the control terminal of the signal generator to produce an impedance adjustment signal on the current electrode for communication to the power generator through the power line in response determining the impedance.
