Inventor: TAKAYA MANABU
IPC: G09F9/00
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To employ a normal insulation step-up transformer even when a rod-like single layer winding transformer having a primary winding in the center is employed. SOLUTION: When a thydac 5 is switched to feed a pulse voltage from a capacitor 4 to the primary winding 61 of a step-up transformer 6, a step-up voltage is induced in the secondary winding 62 of the transformer 6. The step-up voltage charges a capacitor 8 through a circuit of a diode 7, the capacitor 8 and the secondary winding (s) of a pulse transformer 10. When the charging voltage of the capacitor 8 increases to conduct a gap 9, a high voltage is inputted to the primary winding (f) of the pulse transformer 10 and a high voltage is induced in the primary and secondary windings (f), (s) of the pulse transformer 10. The diode 7 is biased reversely by the high voltage which is thereby blocked by the diode 7 and not applied to the secondary winding 62 of the step-up transformer 6.  Consequently, a normal insulation can be employed between the primary and secondary windings 61, 62 of the step-up transformer 6.
