A deflection generator of a television receiver is coupled to a deflection winding for generating scanning current during a deflection cycle. The generator includes a retrace capacitor coupled to the deflection winding for forming a retrace resonant circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor and another capacitor form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement is coupled to a source of energy and the second resonant circuit in a push-pull configuration. The switching arrangement is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source in the second resonant circuit. This stored energy is then transferred to the retrace resonant circuit during the retrace interval to replenish losses sustained during the deflection cycle. |
