ABSTRACT:
A television horizontal deflection circuit is provided with a flyback transformer and a switching regulator transformer which are substantially magnetically independent of each other and which are connected with their primaries in series with a switching device and a source of input voltage. The secondary winding of the switching regulator transformer supplies power to a regulated D.C. voltage supply, which in turn supplies power to a resonant circuit. The resonant circuit is connected to a reference potential through the switching device and includes a damper diode, a resonant capacitor, a deflection coil and a series connected capacitor. A secondary winding of the flyback transformer is used to derive a high voltage for use in the high voltage anode of a television picture tube. In a preferred embodiment, the flyback transformer contains an additional winding which is connected between the regulated D.C. voltage supply and the resonant circuit. This additional or feedback winding is inductively coupled with the primary winding of the flyback transformer so that the flow of current through that primary winding while the switching means is conductive will impede the flow of current from the regulated D.C. voltage supply to the resonant circuit.
