Document Type and Number:
Japanese Patent JP2000511348
Kind Code:
A
Abstract:
A controllable inductor comprises at least a tubular core, a main winding surrounding the core and a control winding passing substantially axially through the core. A yoke of a material having a high magnetic permeability is arranged to extend outside the core and the main winding and together with the core form a closed loop having at the most small air gaps for a main magnetic flux generated in the core by a current in the main winding and extending substantially axially to the core. The control winding comprises first plates of a material having a good electric conductivity extending substantially axially through the core.
