Abstract
An adjustable inductor and a method of assembling such an inductor. The inductor may include a toroidal core defining a pair of gaps to provide a removable core section, the core also including a rigid core section; compressible gap material positioned in the gaps; windings wound on the rigid core section; and force-applying structure operable to apply a force to the removable core section to adjust the gaps and thereby the inductance.
Claims26
An inductor comprising:
- a toroidal core defining two gaps to provide a removable core section, the core also including a rigid core section;
- compressible gap material positioned in the gaps;
- at least one winding wound on the rigid core section;
- and
- force-applying structure operable to apply a force to the removable core section to adjust the gaps and thereby an inductance of the inductor.

An inductor comprising:
- a wound toroidal core cut to define two gaps and provide a removable core section, the core also including a rigid core section;
- compressible gap material positioned in the gaps;
- at least one winding wound on the rigid core section;
- and
- at least one clamp operable to apply a force to the removable core section to compress the compressible material to thereby adjust the gaps and an inductance of the inductor.
2 more elements
A method of assembling an inductor, the method comprising:
- forming a toroidal core defining two gaps to provide a removable core section, the core also including a rigid core section;
- positioning at least one winding on the rigid core section;
- and
- after positioning the at least one winding, adjusting at least one the gaps and thereby an inductance of the inductor.
