PURPOSE:To reduce occurrence of the fault and thus to enhance the reliability by setting the output voltage of the rectifier circuit higher than the input of the high voltage control circuit and lower than the active voltage of the control circuit each at the normal operation time and using only one unit of the S-shaped capacitor. CONSTITUTION:Transistor Tr1 performs the switching action, and S-shaped capacitor 6 connected in series to damper diode 3, flyback resonance capacitor 4, horizontal deflectng coil 5, flyback transformer 7 and coil 5 is connected to the output circuit of Tr1. Then the output rectifier circuit 9 is connected to the input of high voltage control circuit 16 in order to secure the output voltage of circuit 9 which is higher than the input and lower than the acdtive voltage of circuit 16 each at the normal operation time. As a result, the fault can be reduced with enhancement of reliability for the S-shaped capacitor with use of just one unit of capacitor 6. |
