PROBLEM TO BE SOLVED: To evenly cool the primary winding and the secondary winding of a transformer, as well as to be able to adjust a leakage inductance of the transformer.SOLUTION: The present invention is configured, in a winding 2, with a primary winding 2a, a gap 2b provided with an insulation sheet, and a secondary winding 2c wound over the gap 2b, in order of proximity from the center of a core 1, and configured, in a winding 3, with a secondary winding 3c, a gap 3b provided with an insulation sheet, and a primary winding 3a wound over the gap 3b, in order of proximity from the center of the core 1. The primary winding 2a and the primary winding 3a are connected by a primary winding heat transfer path 5, and the secondary winding 2c and the secondary winding 3c are connected by a secondary winding heat transfer path 6, with the secondary winding 2c and the primary winding 3a brought into contact with a cooling surface of a heat sink 4. |
