Abstract:
1. A method for the transmission of energy and data, wherein a primary side with an amplifier with a connected primary winding and a secondary side with a data source are provided, wherein said data source is a digital sensor with a connected secondary winding, comprising the steps of: inductively coupling, galvanically completely isolating the amplifier and the data source by means of a plug-together assembly; inductively transmitting energy from the amplifier to the data source on the secondary side, and inductively transmitting data in the opposing direction from the data source to the amplifier; controlling the power drawn by the plug-together assembly and the data source by means of a microcontroller, wherein said microcontroller is situated on the primary side; controlling the operating frequency for the amplifier by means of the microcontroller as a function of primary voltage on said primary winding; and controlling the operating voltage for the amplifier by means of the microcontroller as a function of the primary voltage on said primary winding, wherein said microcontroller receives said primary voltage from said primary winding and produces and controls, as a function of the primary voltage, said operating frequency and said operating voltage for said amplifier, wherein said microcontroller controls a DC-DC converter for producing said controlled operating voltage for said amplifier, wherein on the input of said DC-DC converter lies a voltage delivered by a measured value transmitter, wherein said amplifier is a Class-E amplifier, wherein connected to the output of said Class-E amplifier is said primary winding, wherein said secondary winding is connected to a combined input and output of the digital sensor, and wherein said primary winding and said secondary winding are arranged in said plug-together assembly.
