Abstract
A high-voltage stabilizer circuit cooperates with the flyback transformer in a cathode ray tube display system to prevent level variations in the video signal from producing corresponding variations in the high-voltage output from the flyback transformer to the cathode ray tube, such high-voltage variations being undesirable because they result in changes in the electron beam position on the phosphor screen that produce shifts in the resultant picture. The current flowing through the video circuit is controlled inversely in relation to variations in the cathode current of the cathode ray tube so that the high-voltage output from the flyback transformer remains constant. This high-voltage stabilizer involves specific choices of circuit element values and is particularly suitable for so-called flat-tube television receivers.
