Deflection and high voltage circuit |
摘要 |
A deflection and high voltage circuit produces a proper luminance level and a focusing performance in a CRT image irrespectively of changes in a luminance signal level. The circuit is provided with a voltage control circuit for controlling an output voltage level of a voltage supply circuit according to changes in the anode voltage of the CRT so that a voltage obtained by rectifying a voltage generated by the secondary winding of flyback transformer, i.e., the anode voltage of the CRT is made constant. Furthermore, the circuit is provided with a correction circuit for preventing a voltage across the terminals of a S-curve correction capacitor determining the H-size of the CRT image from being affected by the variation of the output voltage level of the voltage supply circuit.
