<P>PROBLEM TO BE SOLVED: To enhance reliability for core crack while suppressing corona discharge. <P>SOLUTION: The transformer includes a bobbin 8 having a through hole 9 and a plurality of split winding grooves 12, a rod-like core 10 to be inserted into the through hole 9, primary windings 13, 14 and secondary windings 15, 16 wound around the split winding grooves 12, and a case 18 for housing the bobbin 8. In the case 18, the periphery of the bobbin 8 and the rod-like core 10 is sealed hermetically with a filling resin 19. The primary winding is formed by connecting the first primary winding 13 and the second primary winding 14 in series, and the first secondary winding 15 and the second secondary winding 16 of the secondary winding and a diode 17 are connected in series thus forming a transformer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
