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).
