Abstract

In a method and in an apparatus for transmission of energy and data, with a primary side, on which an amplifier is arranged, with a secondary side, on which a data source, e.g. a measuring sensor, is arranged, and with a plug-together assembly inductively coupling, galvanically completely isolated, the primary side and the secondary side, to minimize power losses and disturbing influences of fluctuating parameters, power from the plug-together assembly and from the amplifier, preferably a Class-E-amplifier, is controlled to a predeterminable, desired value. For this, a microcontroller taps the primary voltage on the primary winding and produces for the amplifier a controlled operating voltage as well as a controlled operating frequency, in order to keep the working point of the amplifier always in the optimal region.
