<p>PROBLEM TO BE SOLVED: To simplify the shape of a core 20 to facilitate the forming process thereof and achieve a low cost, and in the case of thin core, make the core difficult to break when it is subjected to contraction due to temperature change or mechanical shock. SOLUTION: An inverter transformer is provided with a pair of butted cores to form a closed magnetic path, one primary winding 1, and a plurality of secondary windings 2, 3 electromagnetically coupled to the primary winding 1. A first leg inserted into the center of the primary winding, and a plurality of second legs inserted into the centers of the secondary windings respectively, are provided on the pair of cores 2, 3, and at least one core is divided into two parts.</p> |
