ABSTRACT:
A component coil for constructing transformers and the transformer constructed therefrom are disclosed. The component coil includes a substrate having an insulating layer of material having top and bottom surfaces. First and second traces are included on the top and bottom surfaces. Each trace includes a spiral conductor. The inner ends of the spiral conductors are connected by a conductor that passes through the insulating layer. The first and second spiral conductors are oriented such that magnetic fields generated by the first and second spiral conductors have components perpendicular to the top surface and in the same direction. The component coils can be used to construct a power transformer or a galvanic isolator.
