Abstract
Four metal foil windings can be bonded to the inside of a magnetic core, each in a 90 degree helix. Very simple direct and straight connections can connect the windings to the windings of another similar core in a flat transformer module with no crossovers or overlaps. The center-tap and output terminations are located similarly to the two turn version of the flat transformer module, but make a module with four turns. This may be used as a push-pull winding having two turns on each side of the center-tap, or it may be used as a four turn winding, as, for instance, with a full bridge rectifier in a power converter.
