Abstract

A circuit arrangement for the inductive transfer of energy is disclosed. The circuit arrangement includes an oscillator; a power supply for supplying the oscillator with energy and having a complex input resistance; and a device for detecting the inductive load of the oscillator and for modifying the complex input resistance of the power supply depending on the load of the oscillator.
