Abstract

A deflection circuit for a television receiver comprises a deflection winding coupled to commutating and trace switches. A reactive circuit including a capacitor is coupled between the switches. A transient voltage damping circuit is coupled across the commutating switch. The damping circuit includes a transformer comprising a primary winding to which the transient voltages are coupled and a secondary winding coupled to an auxiliary load circuit.
