Abstract
The device has a primary coil (4) for transmitting energy to a mobile sensor unit (3) when a secondary coil is in a magnetic field. A base unit has a capacitor that forms an oscillating circuit with the primary coil, and a control circuit for measuring voltage at the capacitor. The control circuit detects deviation of the voltage from maximum voltage with resonance frequency of the oscillating circuit with detuning of the oscillating circuit by the sensor unit. The control circuit corrects the frequency of the oscillating circuit such that the voltage at the capacitor is maximized.
