Abstract: A voltage regulator provides a regulated B+ voltage to the horizontal deflection circuit of a television receiver. A positive feedback loop senses the load current drawn by the deflection circuit. The positive feedback voltage increases the magnitude of a reactive impedance component of the voltage regulator as the load current increases in order to maintain a substantially constant raster width.

Abstract: A television deflection apparatus includes a deflection winding coupled to a retrace capacitance to form a retrace resonant circuit. A power transistor switch is coupled to the retrace resonant circuit for generating alternating current in the retrace resonant circuit. The power transistor switch energizes a primary winding of a flyback transformer that supplies a first voltage across a secondary winding of the flyback transformer. The first voltage is coupled to an inductance for forming an upramping current in the inductance. The upramping current in the inductance is coupled to the base electrode of the power transistor switch, causing the power transistor switch to be conductive during the second half of trace. A second switch, that is responsive to a deflection rate input signal, couples to the base electrode of the power transistor switch a negative supply voltage that turns off the power transistor to initiate the retrace interval.

Abstract: Line and field deflection circuits generate line and field deflection currents in respective line and field deflection windings to scan a raster on the phosphor screen of a square-planar picture tube having an aspherical faceplate. The asphericity of the faceplate subjects the scanned raster to gullwing distortion. A gullwing distortion correction circuit is responsive to signals repeating at line and field rates, respectively, for modulating the field deflection current during a line deflection period within the field deflection trace interval in a manner that corrects gullwing distortion of a corresponding raster scan line.

Abstract: A primary winding of a power transformer is coupled to a source of DC voltage. First and second controllable switches are coupled to the primary winding in a push-pull arrangement. A control circuit responsive to a deflection rate input signal that is synchronized with deflection circuit scanning applies a turn-off switching signal alternately to the two controllable switches during each deflection cycle. In response to the turnoff of each one of the two controllable switches, a turn-on switching signal is applied to the other switch to develop a deflection rate alternating polarity output voltage across an output winding of the power transformer. The output voltage is rectified and applied to a deflection generator to thereby energize the generator into developing scanning current in a deflection winding.

Abstract: In a remote controlled television receiver, the regulator circuit of the main television receiver power supply is made responsive to a remote on/off command signal in order to turn the receiver on and off. A deflection flyback transformer provides operating voltages to the ultor supply and other auxiliary supplies which power such load circuits as audio and vertical deflection. A horizontal output transistor is coupled to a B+ operating voltage terminal of the main power supply through a flyback transformer primary winding. After initiation of the on-state of the command signal, the regulator ciruit rapidly develops a B+ operating voltage. The initially uncharged filter capacitors of the auxiliary supplies act as a low impedance shunt across the flyback transformer primary winding during the start-up interval. To limit the horizontal output transistor collector current and power dissipated during start-up, the horizontal driver stage holds the forward base current supplied to the horizontal output transistor each deflection cycle during start-up below the steady-state value.

Abstract: A horizontal deflection system is operable either from rectified and filtered alternating current line voltage or from a substantially lower voltage direct current voltage source. The need for a step-down transformer in the receiver power supply is eliminated by utilizing the horizontal output transformer to drop the rectified and filtered alternating current voltage when the receiver is operated in the alternating current line mode. The horizontal output transformer is utilized as a step-up inverter when the receiver is operated from the low voltage direct current source to produce a direct current voltage at a point on the horizontal output transformer substantially equal to the rectified and filtered alternating current line voltage.
