<p>PURPOSE: To lessen a fly-back transformer in load variation and load variation size by a method wherein the ends of a first split coil of split coils which form a high voltage coil are positioned inside those of a second split coil, and the first split coil is specified in winding width and wire diameter. CONSTITUTION: A pressure coil is composed of split coils K1, K2, K3... and Kn, wherein the first split coil K1 is set 0.7 to 0.9 times as wide as the second split coil K2 in winding width. When the first split coil K1 is wound on the peripheral surface of a high-voltage bobbin, the ends T1 and T2 of the first split coil K1 are positioned between the ends T3 and T4 of the second split coil K2. Moreover, the first split coil K1 and the second split coil K2 are usually set equal in number of turns. Furthermore, the first split coil K1 is set thinner than the second split coil K2 in wire diameter.</p> |
