ABSTRACT:
An apparatus for the wireless transmission of energy and data includes a transformer with two sides for transmitting energy in one direction and data in both directions. A circuit on both of the sides of the transformer controls and evaluates a course of the transmission. In a method for controlling and evaluating the apparatus, a primary-side switching path is interrupted for transmitting energy from the primary side to the secondary side. Data are transmitted from the primary side to the secondary side during an energy storage phase by briefly interrupting a primary-side switching path. Data are transmitted from the secondary side to the primary side in a period during an energy storage phase by a secondary-side load pulse. An information transmission is controlled with a trigger and evaluation device on the primary side and on the secondary side. The information both on the primary side and on the secondary side is evaluated in the trigger and evaluation device each communicating with a respective processor.
