Abstract:
1. A configurable transformer module, comprising: a primary printed circuit board having planar primary windings formed thereon, the primary printed circuit board including openings for accommodating a planar transformer core, the planar primary windings encircling a first opening accommodating a center-leg of the planar transformer core; a first secondary printed circuit board, the first secondary printed circuit board having planar secondary windings formed thereon and including an opening for accommodating the center-leg of the planar transformer core where the planar secondary windings encircle the opening, the first secondary printed circuit board having mating terminals formed thereon; a first interface connector formed on the primary printed circuit board to enable electrical connection to the first secondary printed circuit board and to facilitate physical connection of the primary printed circuit board to the first secondary printed circuit board to form the transformer module, the mating terminals formed on the first secondary printed circuit board being electrically connected to the first interface connector, the first interface connector being electrically insulated from the planar primary windings formed on the primary printed circuit board; and a first configuration connector module coupled to the first interface connector formed on the primary printed circuit board to configure the planar secondary windings on the first secondary printed circuit board to realize a given transformer turns ratio between the first secondary printed circuit board and the primary printed circuit board, the first configuration connector module comprising a plurality of programming terminals corresponding to the mating terminals formed on the first secondary printed circuit board, the programming terminals being interconnected to configure the planar secondary windings of the first secondary printed circuit board.
