PROBLEM TO BE SOLVED: To solve a problem that in a control method of high voltage power source in which 2 general purpose power source transformers are used for requirement for increase in electrifying quantity from the view point of cost and 2 systems are separately controlled by PWM signals, difference between 2 output current values is caused and fine control of the electrifying quantity is difficult, and also the cost increases for the complicated circuit. SOLUTION: In the device, power source circuits of plural systems utilizing the general purpose transformers are controlled in common by 1 control part.
