摘要： A power line communication device including a current path provided between a first terminal and a second terminal. A coupling circuit connected between the first and second terminals includes a first circuit of a first inductor connected in parallel with a first capacitor and a first resistor. A sensor is configured to sense a communication parameter of the coupling circuit. The communication parameter may be a resonance of the first circuit, the quality (Q) factor of the resonance, the bandwidth (BW) of the coupling circuit, the resistance of the first resistor, or the impedance of the first circuit. A transceiver is adapted to couple to the first and second terminal to transmit a signal onto the current path or receive a signal from the current path responsive to the parameter of the coupling circuit and a level of current in the current path sensed by the sensor.

摘要： Embodiments described herein may relate to power-line communication (PLC) systems that are suitable for high-voltage and electrically noisy applications. In one example system, PLC technology is used to carry data on at least one pair of conductors of a high-voltage (e.g., kilovolt) transmission line that is simultaneously used for power transmission. Further, in some instances, the transmission line may be part of a tether that connects an aerial vehicle to a ground station.

摘要： A power/data electrical coupler, designed to send over a two-wire bus or to receive therefrom data signals and to deliver to said two-wire bus or receive therefrom a power-supply potential. Such a coupler includes a transformer, a first winding of which and a second and third winding of which are connected in series with each other with a common terminal connected to a power supply line and the other two terminals to a two-wire bus. It also includes a second isolation transformer connected between said first transformer and said two-wire bus. According to the invention, said terminal common to said second and third windings is connected to said power supply line by means of a band-rejection filter rejecting one or more of the frequency bands including the resonant frequency or frequencies resulting from the association of the isolation transformer and the transformer.

摘要： The invention relates to a communication device using power line communication provided in a first system coupled to a second system via a power cable comprising a pilot line having a first impedance, which encounters at least second and third impedances and through which a first analog signal passes in a first frequency band. The device is arranged so as to: i) generate, from a local digital signal, a second analog power line communication signal having frequencies included in a second frequency band that has minimal overlap with the first frequency band; ii) supply the second analog signal to the pilot line via a capacitive means and iii) extract, from the analog signals passing through the pilot line, each second analog signal in order to convert the latter into a digital signal to be processed by the system.
