Abstract:
1. A system for wireless transmission of electrical energy comprising at least a first induction element ( and at least a second induction element ( in which the induction elements ( wherein in the primary circuit (P) means ( so that in the first induction element ( characterized in that in the primary circuit (P) means for setting the frequency of the AC voltage are provided, wherein responsive to an information signal representative of a change in degree of magnetic coupling between the first and second induction elements and thus a corresponding change in resonance in the primary circuit (P), the AC voltage frequency setting means changes an excitation frequency of the AC voltage supplied to the first induction element to make specific use of the change in resonance resulting from positional or locational changes of the induction elements in relation to each other.
