Abstract (en)
[origin: EP1408456A2] A supply induction coil transfers energy to a supplied induction coil. Power is transmitted from the door frame (5) onto the door leaf (6) in the region of a lock or access control device in the door, by inductive power transmission via resonant circuits on the transmission and reception sides. The coupling of the circuits is variable and corresponding coupling effects are compensated.
