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 and to reduce the coupling of the transformer by increasing the leakage inductance. The embedded transformer device provides better isolation between input side and output side windings, and allows an oscillating LC circuit to be set up in the case of a short circuit, preventing high power from extending between the input and output terminals and thereby avoiding damage to the connected electrical components.

Abstract: An embedded magnetic component transformer includes first, second, and auxiliary electrical windings in an insulating substrate including conductive vias joined together by conductive traces. The first electrical windings are divided by a tap terminal into first and second winding portions, which are interleaved with one another and energized by separate transistors. Heat generated by the first and second winding portions is transferred more equally to the separate transistors. Equal or substantially equal path lengths between each of the transistors and the first electrical windings improve flux balance allowing the transistors to conduct for equal or substantially equal times during a switching cycle. Thus, the switching cycle of the embedded transformer is more symmetric with respect to each of the transistors and winding portions, improving the electrical characteristics of the transformer.

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.
