US Patent:

6593836, Jul 15, 2003

Filed:

Jun 28, 1999

Appl. No.:

09/342403

Inventors:

Michael B. LaFleur - East Hampstead NH
Patrizio Vinciarelli - Boston MA

Assignee:

VLT Corporation - San Antonio TX

International Classification:

H01F 2708

US Classification:

336 61, 336 84 R, 336198, 336212, 336219

Abstract:

A bobbin is adapted to support a winding on a permeable core and has a wall that provides a confined thermally conductive channel that causes conduction of heat along a predetermined path from the core to a location outside the winding. A value of magnetizing inductance in a transformer is set by adjusting the gap until the value of magnetizing inductance has been set and attaching a segment of the bobbin to a pair of core pieces to maintain the gap. A permeable strip provides a permeable path outside of the hollow interior space and does not couple the winding, and an electrically insulating coupler is interposed between the slug and the winding to electrically insulate the winding.

US Classification:

174 521, 361760, 361761, 361773

Abstract:

A power converter includes electrical contacts arranged on a first surface and a connection device. The converter has a top surface above the first surface and a bottom surface below the first surface. A border of the bottom surface is inset from a border of the second surface. The connection device includes a pair of conductive legs, each leg comprising a first end and a second end. The pair of legs lie opposite each other in a pair of evenly spaced planes that intersect the first surface. The first ends are adapted to connect to one or more of the contacts on the first surface and the second ends are adapted to connect to one or more conductive pads on a surface of a substrate. The connection device is adapted to enable the first ends of the two legs to connect to the contacts from below the first surface.
