ABSTRACT:
A high-voltage transformer11is provided with first and second bobbins21A,21B wound with primary windings45A,45B and secondary windings46A,46B respectively, I-shaped first and second cores30A,30B fitted into the bobbins21A,21B and an H-shaped third core31interposed between the cores30A,30B. The core30A and core31form a first magnetic circuit and the core30B and core31form a second magnetic circuit, and the primary windings45A,45B around the bobbins21A,21B are wound in the same direction so that the orientations of magnetic flux in both magnetic circuits match inside the core31.
