Abstract
A horizontal deflection circuit output stage generates a retrace pulse in a tertiary winding of a flyback transformer. A flyback pulse that is substantially wider than the retrace pulse is produced in a winding of a second transformer that is coupled in series with the tertiary winding such that the retrace pulse occurs when a peak portion of the flyback pulse is already relatively 'flat'. The amplitude of the flyback pulse is controlled in a negative feedback loop for stabilizing an ultor voltage.
