Abstract
In a system for contactless power and data transmission, a transmitting or receiving station has at least one transmitting or receiving resonant circuit which is driven by an integrable control circuit. The integrated control circuit has a multiplicity of capacitors which can be switched in, in parallel with the resonant circuit. A device is provided for driving the switching device.
Claims6
In a system for contactless power and data transmission between a mobile station and a stationary station, the mobile station comprising:
- a tunable resonant circuit;
- a control circuit driving said resonant circuit, said control circuit having a multiplicity of capacitive circuits including a first capacitor, a second capacitor, a connection node, and at least one switching device;
- said at least one switching device in a given switching state connecting said first capacitor and said second capacitor in series and connecting said resonant circuit in parallel with said series-connected first and second capacitors, and said at least one switching device in said given switching state connecting said connection node between said first capacitor and said second capacitor;
- a device for driving said switching device;
- and
- a terminal for a reference potential to be connected to said connection node.
