Kretskomponent og transformatoranordning med styrbar impedans samt systemerutrustet med slike innretninger

摘要

The invention relates to a circuit component (L 1 ) with controllable impedance, comprising a body ( 1 ) of a magnetisable material, a main winding (A 1 ) wound round the body ( 1 ) about a first axis and a control winding (A 2 ) wound round the body ( 1 ) about a second axis, at right angles to the first axis, where the main winding (A 1 ) is arranged for connection to a working circuit in which the circuit component (L 1 ) is to be employed and the control winding (A 2 ) is arranged for connection to a control unit for controlling the impedance in the working circuit. The invention also relates to various current and voltage regulating devices comprising the circuit component or a similar transformer device.
