US 2026/0204472 A1 · FRACTIONAL MATRIX TRANSFORMER

Abstract

The disclosed concepts relate to a matrix transformer comprising a plurality of ferromagnetic legs, a plurality of primary windings, and a plurality of secondary windings. Each secondary winding is wound around each leg a same number of times. For each leg, the sum of the number of turns made by the plurality of primary windings around the respective leg is the same. Further, a total number of turns made by each respective primary winding around the plurality of legs does not equal an integer multiple of the number of legs. As a result, for a given/target number of legs, and for a given number of turns of the secondary winding, a greater number of turns ratios between the primary and secondary windings are possible, as the restriction of having the number of turns of each primary winding equal to an integer multiple of the number of legs is removed.
