Abstract
An embedded transformer device includes first, second, and auxiliary windings, defined in an insulating substrate by conductive vias joined together by conductive traces. The positions of the conductive vias are arranged to optimize the isolation properties of the transformer, while the conductive traces are arranged to optimize the coupling between the primary and secondary side windings. The embedded transformer device provides favourable isolation and energy transfer between input side and output side windings, in a device with a small component size.
