US Patent:

7477121, Jan 13, 2009

Filed:

Jul 10, 2007

Appl. No.:

11/775760

Inventors:

Arthur Ray Martin - Rowlett TX, US
Roger Dale Grandchampt - Dallas TX, US

Assignee:

Lineage Power Corporation - Mesquite TX

International Classification:

H01F 27/28

US Classification:

336182

Abstract:

An electrical winding structure configured for use in assembling a plurality of electrical winding structures in an installed orientation wound about a central member includes: a unitary segmented strip. First portions of the unitary strip are oriented about a first axis. Second portions of the unitary strip are oriented about a second axis substantially perpendicular with the first axis. Each of the first portions and the second portions have a thickness, have a width greater than the thickness and have a length at least as great as the width. The first and second portions are oriented to effect arranging the electrical winding structure at predetermined loci during winding to clear the winding path to establish a predetermined plurality of strata in the installed orientation.

Appl. No.:

11/751774

Inventors:

Arthur Ray Martin - Rowlett TX, US
Roger Dale Grandchampt - Dallas TX, US

Assignee:

Lineage Power Corporation - Plano TX

International Classification:

H01F 5/00
H01F 27/24

US Classification:

336223, 336232, 336216

Abstract:

An apparatus includes an electrically conductive generally planar strip having a thickness, having a width greater than the thickness and having a length greater than the width. The strip is arranged in alternating length segments. Each adjacent pair of length segments are oriented about divergent axes and are joined by a respective transition arrangement. Each respective transition arrangement presents the strip foldingly lapped upon itself in a laminate structure.

Assignee:

General Electric Company - Schenectady NY

International Classification:

H02M 3/335

US Classification:

363 2102, 323247, 323355

Abstract:

A system is provided having a first LLC power converter and a second LLC power converter. The first LLC power converter comprises a first LLC voltage source. The second LLC power converter also comprises a second LLC voltage source. The first LLC power converter also comprises a first resonant inductor, a first magnetic inductor, and a first resonant capacitor coupled to the first voltage source of the first LLC power converter. The second LLC power converter comprises a second resonant inductor, a second magnetic inductor, and a second resonant capacitor coupled to the second voltage source of the second LLC power converter. The first LLC power converter and the second LLC power converter are both magnetically couplable to a common load. A resonance of the first LLC power converter substantially matches a resonance of the second LLC power converter.

Assignee:

Lineage Power Corporation, a Corp. of Nevada - Plano TX

International Classification:

H01F 17/04
H01F 41/00

US Classification:

336221, 29606

Abstract:

An apparatus for effecting inductive coupling among a plurality of electrical elements includes: (a) an electrically non-conductive core member oriented about an axis; (b) at least one first electrical element of the plurality of electrical elements substantially nestingly surrounding the core member oriented about the axis; each respective first electrical element being in spaced relation vis-à-vis other first electrical elements in an installed orientation; and (c) at least one second electrical element of the plurality of electrical elements disposed in surrounding relation with respect to the core member about the axis sufficiently proximal with at least one selected said first electrical element in the installed orientation to establish the inductive coupling.

Assignee:

Tyco Electronics Power Systems, Inc. - Mesquite TX

International Classification:

H01F 7/06
H01F 27/28

US Classification:

29605, 29596, 29598, 29606, 29609, 2424441, 336182

Abstract:

A method for assembling electrical windings about an axis, the windings being strips and wound in alternating strata with their widths parallel with the axis, includes the steps: (a) Winding a first-wound winding in a winding path about the axis establishing a first stratum. (b) Arranging the first-wound winding to clear the winding path. (c) Winding one or more next windings to establish next-wound windings in the winding path until at least one next stratum is established. (d) Interleaving earlier-wound windings to establish the plurality of strata; the interleaving including the steps of: (1) rearranging a next-to-be-wound winding to realign with the winding path; (2) winding the next-to-be-wound winding in the winding path until a next stratum is established; (3) arranging the next-to-be-wound winding to clear the winding path; and (4) repeating steps (d)(1) through (d)(3) until the assembling is complete.
