PROBLEM TO BE SOLVED: To obtain a high-voltage generating circuit which generates a high voltage supplied to a CRT, etc., and can reduce losses caused by overshooting and undershooting, generated by a current applied to the primary winding of a transformer, when a switching device for generating a flyback pulse is turned on. SOLUTION: The operation of a switching device in the primary side circuit of a high-voltage generating circuit is adjusted, so as to turn on the switching device near the bottom of a halt oscillation pulse generated, after a flyback pulse obtained by the on/off operations of the switching device. With such a constitution, overshooting and undershooting of a current applied to the primary winding of a transformer can be suppressed. |
