Abstract
The trace switch of a horizontal deflection circuit is coupled to a secondary winding of a flyback transformer. The primary winding is coupled to a source of energy and a regulator switch. A control circuit varies the phase angle of the regulator switch in accordance with an energy level of the deflection circuit. A regulator commutating inductance in combination with a commutating and tuning capacitance controls the duration of conduction of the regulator switch. The capacitance independently tunes with a flyback transformer winding to transfer energy from the source in a resonant manner.
