Device for modifying an AC voltage, AC voltage having a superimposed data signal, method for data transmission, use of a receiver and communication architecture

摘要

A device for modifying an AC voltage has an input for connecting to an AC voltage source and an output for connecting to a load circuit. An interrupter is designed such that, within a time window, the output can be disconnected from the AC voltage source. The time window has a time delay from the zero crossing of the voltage of the AC voltage source. At the output, the device has a terminator that is designed, together with the interrupter, such that the voltage at the output has a predefined or predefinable value in the time window. The device also includes a pulse shape generator for generating a predetermined or predeterminable pulse shape, and a control that actuates the terminator and the interrupter such that the voltage curve at the output can be modified according to the pulse shape predetermined by the pulse shape generator.

1. An apparatus for modifying an AC voltage of an AC power supply system, said apparatus comprising:
an input for connection to an AC voltage source and an output for connection to a load circuit, an interrupter, between the input and the output which at least partially isolates the output from the AC voltage sourced during a time window, wherein the time window is at an interval of time from a zero crossing of the voltage from the AC voltage source, a terminator at the output between a neutral conductor and a conductor, said terminator being designed such that in the time window, the neutral conductor and the conductor at the output to the load circuit are shorted or at least are low impedance loaded such that, together with the interrupter, the voltage at the output of the apparatus has a predefined or predefinable value, a pulse shape generator for generating a predetermined or predeterminable pulse shape, and control means which actuate the terminator and the interrupter to modify the voltage curve, at the output of the apparatus, in accordance with the pulse shape prescribed by the pulse shape generator.
