Patent ID: 6980074

Claim:
A power processing device comprising: (a) a multilayer printed circuit board having multiple layers of dielectric sheets; (b) a first transformer having, 1) a first core extending through said layers of dielectric sheets, and, 2) a first set of electrically conductive windings, at least one of said windings of said first set of electrically conductive windings contained between two adjoining layers of said dielectric sheets; (c) a second transformer having, 1) a second core extending through said layers of dielectric sheets, and, 2) a second set of electrically conductive windings, at least one of said windings of said second set of electrically conductive windings contained between two adjoining layers of said dielectric sheets; and, (d) at least one electrically conductive trace extending between said first set of electrically conductive windings and said second set of electrically conductive windings, said at least one electrically conductive trace contained between two adjoining layers of said dielectric sheets.
