Abstract: A magnetic assembly includes a magnetic core, four primary windings and four secondary windings. The magnetic core includes four lateral legs. The four primary windings and the corresponding secondary windings are magnetically coupled with each other, and the four primary windings and the corresponding secondary windings are wound on the corresponding lateral legs. The winding directions of the four secondary windings on the corresponding lateral legs are identical. A phase difference between a magnetic flux flowing through a specified lateral leg of the four lateral legs and a magnetic flux flowing through an adjacent lateral leg is any value in the range between 150 degrees and 210 degrees. A phase difference between the magnetic flux flowing through the specified lateral leg and the magnetic flux flowing through another adjacent lateral leg is any value in the range between 60 degrees and 120 degrees.
