Abstract

Provided is a transformer (), which includes: a core () which forms a magnetic circuit and has a middle leg () and a plurality of side legs () branched from the middle leg (); primary windings () respectively wound around a first winding leg () and a second winding leg (), which are selected from the middle leg () and the side legs (); and a secondary winding () wound around either of the first winding leg () or the second winding leg (), wherein a first magnetic flux generated by the primary windings () from the first winding leg () and a second magnetic flux generated by the primary windings () from the second winding leg () differ from each other by a predetermined value or more at a position at which the fluxes do not intersect with the secondary winding ().
