摘要：The inductance has a main winding supplied with alternating current around onelimb of a core. In novel design, a control winding on at least one limb of the core issupplied with direct current. The control winding is formed by two partial windings. Thewinding directions are such that the local flux produced by the first partial controlwinding, agrees in direction with that produced in the same region, by a positive current inthe main winding. In addition the flux produced locally by the second partial controlwinding, corresponds in direction with the flux produced locally by negative current in themain winding. The control winding is wound in alternating fashion, so that 1-10 windingsare made in a first region, then another 1-10 windings are laid-on in a second region. Asupply winding is wound on at least one limb of the core. This is connected to a deviceproducing direct current. The device employs an induced voltage, especially a secondaryvoltage, which is sent to the supply winding. The device producing direct current is acontrolled DC/DC converter, power switch and/or controlled resistance. The coreincludes an air gap penetrated by the flux produced by the main winding. The fluxproduced by the partial control windings is passed through regions of the core withoutan air gap. The control signals are transmitted without contact and/or with galvanicisolation. A control circuit is provided. In an arrangement for non-contacting power
transmission (also claimed), a medium frequency current is fed into an extended primaryconductor system. Consumers are supplied using a secondary coil inductively coupledwith the primary conductor system. The secondary coil has a capacitance connected inseries or parallel. The resonant frequency is the medium frequency cited, which liesespecially in the range 10-500 kHz. The novel feature is use of the controlled inductanceas the secondary coil. The inductance is included in a gyrator arrangement. Furtherdetails of this system are included, in accordance with the foregoing principles.
