Magnetic integration of matrix transformer with controllable leakage inductance

A power converter, comprising:

• a matrix transformer, comprising:
• a magnetic core comprising:
• a plurality of core legs, and
• a leakage core leg, the leakage core leg being positioned among the plurality of core legs to control a leakage inductance of the matrix transformer, the leakage core leg between at least two of the plurality of core legs;
• and
• a planar winding structure comprising a primary winding and a plurality of secondary windings, the primary winding extending in a number of turns around the plurality of core legs without a turn around the leakage core leg, the plurality of secondary windings divided into a first set of secondary windings and a second set of secondary windings, the first set of secondary windings having turns arranged around a first set of non-adjacent core legs of the plurality of core legs, the second set of secondary windings having turns arranged around a second set of non-adjacent core legs different from the first set, wherein the turns of the primary winding and the plurality of secondary windings are arranged to create a leakage flux in the leakage core leg to further control the leakage inductance of the matrix transformer;
• and
• a resonant circuit comprising a primary side and a secondary side, the primary side comprising the primary winding of the matrix transformer and the secondary side comprising the plurality of secondary windings of the matrix transformer, wherein the leakage inductance is incorporated into the resonant circuit of at least one of the primary side or the secondary side.
