Beschreibung
Zusammenfassung:	The present invention relates to an inductive contactless power transmitter having a primary side including a first inductor (LP) on the primary side and an oscillator for producing an alternating signal which is supplied to the inductor (LP) on the primary side, and having a secondary side which includes an inductor on the secondary side that can be coupled to the inductor (LP) on the primary side, a load (RL) which is variable in time, and a detection means (42) for determining a power demand of the load on the secondary side, the first oscillator being a voltage-controlled oscillator having a frequency that is adjustable in response to the power demand determined by the detection means (42).
