Title: Three-dimensional coil inductor

Abstract

A three-dimensional coil inductor is disclosed. The inductor includes a substrate; a set of lower electrically conductive traces positioned on the substrate; a core placed over the lower traces; a set of side electrically conductive traces laid on the core and the lower traces; and a set of upper electrically conductive traces attached to the side traces so as to form the inductor. Fabrication of the inductor includes the steps of forming a set of lower traces on a substrate; positioning a core over the lower traces; forming a set of side traces on the core; connecting the side traces to the lower traces; forming a set of upper traces on the core; and connecting the upper traces to the side traces so as to form a coil structure.

Shielded superconducting inductor device

Patent Boom, R; Moses, Jr, R; Peterson, H; ...

The invention discloses an inductor device having a superconducting coil winding capable of maintaining a relatively large current flowing therethrough, and a normal conducting shield winding surrounding the superconducting coil. The superconducting coil and the shield are electrically connected in parallel with the shield functioning to maintain the current and the magnetic field in the superconducting coil substantially constant. The superconducting inductor device can be used to store energy and to return the stored energy to an energy consuming load over a relatively short period without incurring large losses in the superconducting material. This result is obtained by making themore »« less
Microelectromechanical tunable inductor

Patent Stalford, Harold; Hietala, Vincent; Fleming, James

A microelectromechanical tunable inductor is formed from a pair of substantially-identically-sized coils arranged side by side and coiled up about a central axis which is parallel to a supporting substrate. An in-plane stress gradient is responsible for coiling up the coils which. The inductance provided by the tunable inductor can be electrostatically changed either continuously or in discrete steps using electrodes on the substrate and on each coil. The tunable inductor can be formed with processes which are compatible with conventional IC fabrication so that, in some cases, the tunable inductor can be formed on a semiconductor substrate alongside ormore » on top of an IC.« less

Comparative costs of flexible package cells and rigid cells for lithium-ionhybrid electric vehicle batteries.

Technical Report Nelson, P; Jansen, A

We conducted a design study to compare the manufacturing costs at a level of 100,000 hybrid vehicle batteries per year for flexible package (Flex) cells and for rigid aluminum container (Rigid) cells. Initially, the Rigid cells were considered to have welded closures and to be deep-drawn containers of about the same shape as the Flex cells. As the study progressed, the method of fabricating and sealing the Rigid cells was expanded to include lower cost options including double seaming and other mechanically fastened closures with polymer sealants. Both types of batteries were designed with positive electrodes containing Li(Ni{sub 1/3}Co{sub 1/3}Mn{submore »« less

Arrangement of thin film cores for planar coil inductor

Journal Article Matsuki, H; Fujii, N; Shirakawa, K; ... - IEEE Translation Journal on Magnetics in Japan (Institute of Electrical and Electronics Engineers); (United States)

Miniaturized thin film inductors with various shaped magnetic cores are described. The dimensions of these inductors are about 2 mm x 2 mm. Since they are used at frequencies above 100 MHz, the effective utilization of the magnetic core must be considered. The authors measured the inductance of inductors with magnetic cores of various shapes, and investigated the flux density distribution. The inductors were based on from 100 to 240 core pieces, each piece with from one to three coil turns. The conductor of these inductors was confined to a single plane to prevent connection defects. According to measured results,more »« less
