Abstract
An inductor assembly includes a coil including a spirally wound metal foil.
Claims16
An inductor assembly comprising:
- a coil including:
- a spirally wound first metal foil;
- a second metal foil spirally co-wound in face-to-face electrical contact with the first metal foil to form a multilayer conductor;
- and
- an electrical insulator sheet spirally co-wound with the first and second metal foils:
- wherein:
- the first metal foil and the second metal foil are not bonded to one another across their widths;
- and
- the first metal foil and the second metal foil are not bonded to the electrical insulator sheet across their widths.

A multi-unit inductor system comprising:
- a first inductor assembly including a first coil, the first coil including a spirally wound first metal foil;
- and
- a second inductor assembly including a second coil, the second coil including a spirally wound second metal foil;
- wherein the first coil is electrically connected to the second coil;
- and
- wherein:
- the first coil has a first coil longitudinal axis;
- the second coil has a second coil longitudinal axis;
- each of the first and second inductor assemblies includes:
- a first terminal bus bar connected to the coil thereof and projecting outwardly from an axial end of the inductor assembly;
- and
- a second terminal bus bar connected to the coil thereof and projecting outwardly from the axial end of the inductor assembly;
- wherein the first and second inductor assemblies are positioned side-by-side and the first terminal bus bar of the second inductor assembly is electrically connected to the second terminal bus bar of the first inductor assembly.

A method for forming an inductor assembly, the method comprising:
- spirally co-winding a first metal foil, a second metal foil, and an electrical insulator sheet;
- wherein the first metal foil and the second metal foil are co-wound in face-to-face electrical contact with one another to form a multilayer conductor;
- and
- wherein, during the step of spirally co-winding the first metal foil, the second metal foil, and the electrical insulator sheet:
- the first metal foil and the second metal foil are not bonded to one another across their widths;
- and
- the first metal foil and the second metal foil are not bonded to the electrical insulator sheet across their widths.
4 more elements
An inductor assembly comprising:
- an enclosure having a terminal opening and defining an internal chamber;
- a first coil disposed in the internal chamber, the first coil including a spirally wound first metal foil;
- a second coil disposed in the internal chamber, the second coil including a spirally wound second metal foil;
- a terminal bus bar electrically connected to the first metal foil and including a terminal, the terminal busbar including:
- a contact leg disposed in the internal chamber and electrically connected to the foil of the first coil;
- a terminal leg extending out from the housing;
- and
- a connector leg disposed in the internal chamber and joining the contact leg to the terminal leg;
- and
- an electrically insulating polymeric tube surrounding a length of the terminal busbar extending through the internal chamber, through the terminal opening, and outwardly beyond the terminal opening, including a portion of the connector leg extending adjacent the second coil along a length of the second coil.
