Abstract
Abstract A magnetic device and a method of manufacturing the same. In one embodiment, the device includes: (1) a magnetic core and (2) a winding structure located proximate the magnetic core. The winding structure includes:(2 a ) a multilayer main circuit board containing an interconnected first plurality of winding layers, (2 b ) a multilayer overlay board located proximate the main circuit board and containing an interconnected second plurality of winding layers and (2 c ) conductors coupling the first and second pluralities of winding layers together to cause the first and second pluralities of winding layers to function cooperatively as windings for the magnetic device.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
81 words
A magnetic device, comprising: a magnetic core; and a winding structure, located proximate said magnetic core and including: a multilayer main circuit board containing an interconnected first plurality of winding layers, a multilayer overlay board located proximate said main circuit board and containing an interconnected second plurality of winding layers, and conductors coupling said first and second pluralities of winding layers together to cause said first and second pluralities of winding layers to function cooperatively as windings for said magnetic device.
Claim 2
Dependent Claim
81 words
A magnetic device, comprising: a magnetic core; and a winding structure, located proximate said magnetic core and including: a multilayer main circuit board containing an interconnected first plurality of winding layers, a multilayer overlay board located proximate said main circuit board and containing an interconnected second plurality of winding layers, and conductors coupling said first and second pluralities of winding layers together to cause said first and second pluralities of winding layers to function cooperatively as windings for said magnetic device.
