Data transmission device for use in electrical consumer, has secondary inductor inductively coupled to primary inductor, and series resonance circuit connected parallel to another series resonance circuit and coupled to primary inductor

摘要

The device (10) has a secondary inductor (L1) inductively coupled to a primary inductor (L4) and supplemented by a capacitor (C1) at a series resonance circuit (13). The resonance circuit is connected with an output of an electronic signal source. Another series resonance circuit (14) having another capacitor (C2) and another secondary inductor (L2) is connected parallel to the former series resonance circuit, and is coupled to the primary inductor, where resonance frequencies of the respective resonance circuits are different from each other. An independent claim is also included for a system comprising an electrical consumer.
