1. A DC/AC converter system having contactless, inductive energy transfer comprising:
- an electronic high-frequency pulse generator including a first magnetic core coupled with a primary winding; and
a user circuit configured to inductively couple with the electronic high-frequency pulse generator, the user circuit including a second magnetic core coupled with an associated secondary winding;
wherein the second magnetic core is configured to magnetically couple with the first magnetic core when placed in one of at least two predetermined positions with respect to the first magnetic core and a corresponding prescribed level of energy transfer results for each of the at least two predetermined positions.

Abstract
A DC/AC converter is provided for contactless, inductive transfer of energy, which transfers arbitrary voltages to a removable user with the aid of a high-frequency pulse generator. The pulse generator produces asymmetric pulses, which provides two different voltages to the user, depending on a coupling orientation. Further, the pulse generator is built in such a way that, if a user is absent, it is not excited to oscillation and, as a result, uses substantially no energy at all in a stand-by operation.
