Zusammenfassung: | A trace current is generated in a horizontal deflection winding upon closure of a trace switch. A retrace capacitor forms a resonant retrace circuit with the deflection winding upon open-circuiting of the trace switch. A second resonant circuit is coupled to an energy supply and stores energy when the trace switch is closed. A second switch couples the resonant retrace circuit to the second resonant circuit during retrace. The stored energy in the second resonant circuit is then transferred to the resonant retrace circuit and to other load circuits, such as a flyback transformer. |
