Abstract

A system for contactless data and power transmission between a first vehicle component and a second vehicle component includes a first control unit, a second control unit, and a transducer with a primary winding and a secondary winding. The first control unit is adapted to generate an alternating voltage at a signal output port from a voltage present at a voltage input port, where the frequency of the alternating voltage is modulated depending on the data that is input at a data input port, and wherein the second control unit is adapted to demodulate the data and provide it at the data output port.
