Integrated magnetic transformer assembly

The present invention relates to an integrated magnetics transformer assembly comprising a first magnetically permeable core forming a first substantially closed magnetic flux path and a second magnetically permeable core forming a second substantially closed magnetic flux path. A first input inductor winding is wound around a first predetermined segment of the first magnetically permeable core and a second input inductor winding is wound around a first predetermined segment of the second magnetically permeable core. The integrated magnetics transformer assembly further comprises a first output inductor winding comprising series coupled first and second half-windings wherein the first half-winding is wound around a second predetermined segment of the first magnetically permeable core and the second half-winding is wound around a second predetermined segment of the second magnetically permeable core. A second output inductor comprises series coupled first and second half-windings wherein the first half-winding is wound around a third predetermined segment of the first magnetically permeable core and the second half- winding is wound around a third predetermined segment of the second magnetically permeable core. The second half-winding of the first output inductor winding and the second half-winding of the second output inductor winding are configured to produce oppositely directed magnetic fluxes through the second substantially closed magnetic flux path and the first half-winding of the first output inductor winding and the first half-winding of the second output inductor winding are configured to produce aligned, i.e. in the same direction, magnetic fluxes through the first substantially closed magnetic flux path. The integrated magnetics transformer assembly is well- suited for use in a broad range of single input or multiple-input isolated power converter topologies.
