Power converter using orthogonal secondary windings

摘要

A power conversion device includes a magnetic core; and a plurality of windings surrounding portions of the magnetic core, including a first set of windings defining a first magnetic flux path, a second set of windings defining a second magnetic flux path magnetically orthogonal to the first magnetic flux path, and a third set of windings. Each winding of the third set of windings is configured to be excitable via both the first flux path and the second flux path.

1. A power conversion device comprising:
a magnetic core having first, second, and third legs, the first leg being between the second and third legs; and a plurality of windings surrounding portions of the magnetic core, including a first set of windings around the first leg and defining a first magnetic flux path, a second set of windings around the second and third legs and defining a second magnetic flux path, and a third set of windings around the second and third legs; wherein magnetic flux in both the first magnetic flux path and the second magnetic flux path induces a current in each winding of the third set of windings, and the first set of windings are magnetically orthogonal to the second set of windings, such that magnetic flux in the first magnetic flux path does not induce current in the second set of windings and magnetic flux in the second magnetic flux path does not induce current in the first set of windings.
