Abstract:
Disclosed examples include integrated magnetic circuits for LLC resonant converters, including an inductor cell and multiple transformer cells with cores arranged in a stack structure. The individual transformer cells include primary and secondary windings extending around the transformer core structure, and a secondary transistor connected in series with the secondary winding. One or more windings are shaped near core stack gaps to reduce core and winding losses. The inductor cell includes an inductor winding extending around the inductor core structure to provide the inductor, and the capacitor. The inductor cell is arranged in the stack structure with the transformer cells to magnetically couple the transformer primary windings, the inductor winding and the transformer secondary windings in a single magnetic circuit to cancel cell to cell flux.

Claim (Index 16):
A power conversion apparatus comprising:\n a primary circuit having a first primary winding, and a second primary winding coupled in series with the first primary winding; a first secondary circuit having first and second secondary windings coupled in series and interposed by the first primary winding; a second secondary circuit having third and fourth secondary windings coupled in series and interposed by the second primary winding; and a magnetic structure having:\n a first cell structure receiving the first primary winding and the first and second secondary windings; and \n a second cell structure receiving the second primary winding and the third and fourth secondary windings, the second cell structure stacked against the first cell structure to align the first and second primary windings, and the first, second, third, and fourth secondary windings along an axis.
