Method of tuning a flyback transformer for minimum ringing

The method of optimizing a flyback transformer in a cathode ray tube control system for minimum ringing, comprising the steps of;

• (a) placing in said system a standard flyback transformer having a core, a primary or low voltage coil, and a secondary or high voltage coil;
• (b) placing a suitable sensor in the vicinity of said high voltage coil to pick up a signal, which is a function of the voltage waveshape in said high voltage coil, and displaying said pickup signal on a cathode ray oscilloscope;
• (c) positioning said primary at a selected position, and relatively displacing and adjusting the central plane of said high voltage coil laterally with respect to the central plane of said primary coil, while noting the amplitude of ringing in said pickup signal, until a selected relative position is reached, where said ringing is a minimum;
• and
• (d) locking said high voltage and low voltage coils against relative lateral movement at said selected position with respect to each other and to said core.
• whereby said flyback transformer will be tuned for minimum ringing.
