Abstract

A circuit arrangement for the inductive transfer of energy is disclosed. The circuit arrangement includes an oscillator; and a device for detecting the load of the oscillator and for setting the circuit arrangement into one of multiple operating states depending on the detected load. The device determines the load of the oscillator using an electrical variable occurring in the oscillator.
