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 1):
A power conversion apparatus comprising:\n a first primary circuit having a first primary winding; a second primary circuit having a second primary winding; an inductor having an inductor winding coupled in series with the first and second primary windings; a first secondary circuit corresponding to the first primary circuit, and having first and second secondary windings coupled in series; a second secondary circuit corresponding to the second primary circuit, and having third and fourth secondary windings coupled in series; and a magnetic core structure positioning:\n the first primary winding in between the first and second secondary windings, and to overlap the first and second secondary windings along an axis; \n the second primary winding in between the third and fourth secondary windings, and to overlap the third and fourth secondary windings along the axis; and \n the inductor winding to overlap the first and second primary windings, and the first, second, third, and fourth secondary windings along the axis.
