    • The invention relates to a circuit for the inductive transfer of energy to a small-scale electrical unit, said circuit comprising an oscillator (LC), a power supply (N) having a complex input resistance that supplies the oscillator (LC) with energy, and a device for detecting the inductive load of the oscillator and for modifying the complex input resistance of the power supply according to the load of the oscillator (LC). The load of the oscillator and therefore the power requirements of the small-scale electrical unit are determined on the basis of an electrical variable in the oscillator. The invention also relates to a method for the inductive transfer of energy from a circuit to a small-scale electrical unit, the circuit comprising an oscillator (LC), a power supply (N) having a complex input resistance that supplies the oscillator (LC) with energy, and a device for detecting the inductive load of the oscillator and for modifying the complex input resistance of the network component according to the load of the oscillator (LC). In the event of a small load on the oscillator (LC), the active power absorption of the power supply is reduced by modifying the complex input resistance.
