PROBLEM TO BE SOLVED: To prevent oscillating current due to an LC from generating after a damper period by using a flyback pulse as a switch signal and performing on/off of a resonant capacitor about a high-voltage stabilization circuit of a primary current control system of a FBT(flyback transformer) which varies on time of a high-voltage output transistor and stabilizes high voltage. SOLUTION: Between a resonant capacitor 5 and grounds, anode of a diode 14 is inserted to the resonant capacitor connected with the diode 14, a collector is inserted to a bipolar type PNP transistor 15 that is connected to the resonant capacitor in the same way and the transistor 15 is a high-voltage stabilization circuit of a primary current control system which is provided with a switching circuit that performs on/off operations with a flyback pulse that is obtained from a tertiary winding of an FBT. |
