Abstract
Method for transmitting charging signals via a data transmission path using resonance phenomena The invention provides a method for transmitting charging signals, in which an electrical resonance effect is provided, with an output current (100) being emitted from a line current driver device (202), which output current (100) is passed through a data path filter block (201), which has a data transmission path unit (122) and a matching filter unit (123), to a line impedance (102), and the matching filter unit (123) and the data transmission path unit (122) are set such that an electrical resonance effect occurs, which leads to a voltage peak occurring in a line voltage level (101).
Claims8
A method for transmitting charging signals, in which an electrical resonance effect is provided, the method comprising:
- a) emitting an output current from a line current driver device;
- b) passing the output current through a data path filter block, which has a data transmission path unit and a matching filter unit, to a line impedance;
- and
- c) setting the matching filter unit and the data transmission path unit such that a series tuned circuit is formed and an electrical resonance effect occurs, which leads to a voltage peak being produced in a line voltage level, wherein a circuit in the line current driver device is provided such that circuit components of the data transmission path unit and of the matching filter unit form a parallel tuned circuit.
An apparatus for transmitting charging signals, with an electrical resonance effect occurring, the apparatus comprising:
- a) a line current driver device for emission of an output current;
- and
- b) a data path filter block through which the output current is passed to a line impedance, and which comprises a data transmission path unit and a matching filter unit, wherein the matching filter unit and the data transmission path unit form a series tuned circuit and are set such that an electrical resonance effect occurs, which leads to a voltage peak being produced in a line voltage level, wherein circuit components of the data transmission path unit and of the matching filter unit form a parallel tuned circuit.
