Abstract (en)

A method for setting a desired value of winding inductance in a magnetic component of the kind having a permeable core structure which defines a magnetic flux path and has a gap along the path. The method includes: a. measuring the actual value of the inductance of the winding; and b. automatically changing the gap length to cause the actual value to approach the desired value. Apparatus for setting the desired value of inductance includes: a. inductance measurement circuitry having a port for connection to the magnetic component; and b. a device having a movable support for the core structure and a controller configured to automatically change the gap length to cause the actual value to approach the desired value. <IMAGE>
