Abstract
Method for wirelessly transmitting energy from a primary device (1) to an implantable secondary device (2), wherein the primary device includes a primary coil (11) and the secondary device (2) includes a secondary coil (12) for electromagnetic interaction with the primary coil (11), with a control process which includes: measuring a primary current flowing through the primary coil (11) and a primary voltage applied to the primary coil, calculating a secondary current of the secondary coil (12) and a secondary voltage of the secondary coil (12) on the basis of the measured primary current and the measured primary voltage, comparing the calculated secondary current with a desired secondary current and/or the calculated secondary voltage with a desired secondary voltage, predefining a desired primary current and a desired primary voltage on the basis of the comparison, and operating the primary coil with the desired primary voltage and the desired primary current in order to transmit energy to the secondary coil (12).
