Abstract
A bobbin for hybrid coils in planar magnetic components is disclosed. An outer bobbin component is configured to hold planar magnetic circuits comprising between one and twenty different windings. An inner bobbin component holds a conventional winding of a multitude of round-section insulated conductor wires. The inner bobbin is shaped for assembly, preferably by a “snap in” configuration, into a space provided at least partially inside the outer bobbin. The bobbin assembly may be used as a transformer with the addition of a ferrous core element magnetically connecting the windings of the two or more bobbins. The transformer is particularly suited for high-frequency high turns ratio duty.
