Abstract
Official abstract text for this publication.
Several embodiments of a circuit device using principles of planar Litz wire construction are disclosed using flexible printed circuit boards on which a given set of conductors is located on one surface only. The FPCBs are folded at strategic locations to effectively cause conductors in adjacent parallel planes to effectively cross one another to realize the advantages of braided Litz wire conductors, but without the use of vias or circuit interconnections between opposite sides of any given FPCB or between different sections of a continuous FPCB wherein each section defines its own coil or coil set.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of constructing a planar litz wire comprising the steps of: providing a flexible printed circuit board (FPCB) having one or more fold lines; locating a plurality of conductors on a side of the FPCB, the plurality of conductors being configured to be electrically in parallel with one another and each conductor of the plurality of conductors having an initial lateral position on the side of the FPCB; and folding the FPCB at least once along the on…
