ABSTRACT:
The device has a primary circuit (1) that transmits energy or data via an intermediate circuit (2) to a secondary circuit (3) by means of induction. The intermediate circuit (2) has a very low quality factor. The inductive coupling between the intermediate circuit (2) and the secondary circuit (3) is reduced by inserting an additional leakage inductor (Ls) so that energy or data is transmitted from the primary circuit (1) to the secondary circuit (3) as effectively as possible. This has the effect of lessening the damping effect of the intermediate circuit (2) on the secondary circuit (3).
