Abstract
A system for contactless power and data transmission contains a stationary station and a mobile station. In order to tune a resonant circuit of the mobile station to the resonant frequency of the stationary station, a multiplicity of capacitors which can be connected in parallel with the resonant circuit are provided. An instantaneous operating state of the system is included in the tuning. The realization is easy to integrate.
