Apparatus and method for wireless data and energy transmission

A method for controlling and evaluating an apparatus for the wireless transmission of energy and data having a transformer with primary and secondary sides and a primary-side switching path, which comprises:

• connecting the primary-side switching path for storing energy at the primary side during an energy storage phase, and interrupting the primary-side switching path for transmitting energy from the primary side to the secondary side during an energy transfer phase;
• transmitting data from the primary side to the secondary side during the energy storage phase by briefly interrupting the primary-side switching path;
• transmitting data from the secondary side to the primary side in a period during the energy storage phase by a secondary-side load pulse;
• controlling an information transmission with trigger and evaluation means on the primary side and on the secondary side;
• and evaluating the information both on the primary side and on the secondary side in the trigger and evaluation means each communicating with a respective processor.

In a method for controlling and evaluating an apparatus for the wireless transmission of energy and data having a transformer with primary and secondary sides and a primary-side switching path being interrupted for transmitting energy from the primary side to the secondary side, the improvement which comprises:

• transmitting data from the primary side to the secondary side during an energy storage phase by briefly interrupting a primary-side switching path;
• transmitting data from the secondary side to the primary side in a period during an energy storage phase by a secondary-side load pulse;
• controlling an information transmission with trigger and evaluation means on the primary side and on the secondary side;
• evaluating the information both on the primary side and on the secondary side in the trigger and evaluation means each communicating with a respective processor;
• transmitting data from the primary side to the secondary side during the energy storage phase, by briefly interrupting the voltage pulse on the primary side resulting in a brief opposite-side phase voltage pulse at the secondary winding, and evaluating a resultant current as data information in a comparator in the secondary-side trigger and evaluation means.
