LOW-VOLTAGE CONTROL INTERFACE COUPLER FOR A MULTI-PULSE EMITTER

摘要

The invention relates to a method for making an oscillation appear in an electricity distribution mains, enabling data to be transmitted. At least one capacitive load (CL) in series with a modulation means are connected between two wires (PH, NL) from the mains. The amplitude modulation means comprises at least one Zener diode (DZ1, DZ2) and at least one switching means (SW1). A short-duration closure pulse (Pi) is applied to the switching means, so that the latter is conducting and short-circuits the Zener diode, thus modulating the amplitude of the mains voltage. The duration of the closure pulse is chosen to be short enough for the amplitude modulation of the mains voltage to cause a response in the mains in the form of a high-frequency oscillation of the mains voltage.
