Abstract

The trace switch 33 of a horizontal deflection circuit 34 is coupled to a secondary winding 23b of a flyback transformer 23. The primary winding 23a is coupled to a source of energy B+ and a regulator switch 24. A control circuit 42 varies the phase angle of the regulator switch 24 in accordance with an energy level of the deflection circuit 34. A regulator commutating inductance 28 in combination with a commutating, and tuning capacitance 29 controls the duration of conduction of the regulator switch 24. The capacitance 29 independently tunes with a flyback transformer winding 23a to transfer energy from the source B+ in a resonant manner.
