ABSTRACT:
A flyback transformer is described for use in television receivers, video monitors, and the like in which a video display device is scanned in accordance with a horizontal retrace frequency. The transformer includes a primary winding for receiving horizontal scan rate pulses and a plurality of secondary windings. The latter windings are tuned to selected harmonics of the horizontal retrace frequency such that at least two secondary windings develop horizontal rate pulses whose peaks are complimentary. The pulses developed by the secondary windings are combined so as to develop a composite pulse whose peak is substantially flat.
