PURPOSE:To suppress generation of a corona, and to check deterioration of an insulator and reduction of output at a pulse transformer by a method wherein a low voltage winding is wound around superposing the edge part of the low voltage side thereof on the edge part of the low voltage side of a high voltage winding. CONSTITUTION:A core 2 is provided inside of a bobbin 1 as occasion demands, and a high voltage winding 3 of secondary winding is wound around the outside periphery of the cylindrical bobbin 1. A low voltage winding 6 of primary winding is wound around the outside periphery of the high voltage winding 3 thereof, and the edge part 7 on the low voltage side of the low voltage winding 6 thereof is wound around superposing on the edge part 4 on the low voltage side of the high voltage winding 3. Therefore, the edge part 8 on the high voltage side of the low voltage winding 6 is positioned on the low voltage side being separated far from the edge part 5 on the high voltage side of the high voltage winding 3, and because an electric potential difference between the edge parts of both the windings is not enlarged according thereto, no corona is generated. Accordingly, rapid deterioration of an insulator due to a corona is eliminated, and moreover output can be enhanced. |
