Abstract: First and second amplifiers which consume varying currents are combined in such a manner as to require a common substantially constant power supply current. An energy storage device coupled to both amplifiers stores energy during periods of low current consumption by the first of the amplifiers. This stored energy is then provided for the second amplifier during periods of high current consumption by the first. A control circuit is provided which allows the first amplifier priority in fulfilling its current requirements.

Abstract: Combined vertical deflection and top and bottom pincushion correction signals are applied to a single amplifier circuit which provides the required vertical deflection n output current as well as pincushion correction signals for a television receiver. Since the frequency of the vertical deflection and pincushion correction signals are substantially different, a series resonant circuit tuned to the horizontal deflection frequency is employed at the output of the amplifier to apply the pincushion signal to the vertical deflection yoke. The resonant circuit includes an inductor which is the primary winding of a transformer whose secondary winding is coupled in series with the vertical deflection yoke to inject the pincushion correction information into the vertical deflection yoke. Negative feedback is employed in the amplifier to preserve the parabolic waveform of the applied pincushion correction signal.

Abstract: A vertical deflection circuit includes a combination oscillatorsawtooth generator. The oscillator-generator includes controls for adjusting the linearity and S-correction functions simultaneously at each portion of the sawtooth waveform corresponding to the top and bottom portions of the raster. A linearity correction network coupled across one portion of a voltage divider in the sawtooth generating circuit affects only a portion of the sawtooth. Another portion of the sawtooth is corrected by a linearity network which decouples a portion of the sawtooth in a driver feedback stage.

Abstract: A raster centering circuit derives it power from a deflection amplifier and has reduced power consumption through the use of energy storage capacitance. In one embodiment a first capacitor coupled to the deflection winding is charged by deflection current through a first diode during a first portion of the trace interval and discharges through a centering control during a second portion of the trace interval, providing a centering current of one polarlity through the deflection winding. A second capacitor coupled to the deflection circuit charges through a second diode during the retrace interval and discharges through the centering control during the trace interval for producing a centering current of the opposite polarlity through the deflection winding. Adjustment of the centering control determines the net flow of centering current through the deflection winding. In another embodiment the junction of the deflection winding and the deflection winding coupling capacitor is coupled through the centering control and through two parallel oppositely poled diodes to ground such that adjustment of the centering control provides a greater deflection current flow through one of the diodes for producing a negative or positive voltage at the capacitor and winding junction for causing the desired polarity centering current flow through the deflection winding.

Abstract: An amplifier derives a substantially constant current from a direct current voltage source. A first output transistor is coupled in an emitter follower configuration and is biased to provide the desired constant current consumption of the amplifier at zero input signal voltage. The load circuit is alternating current coupled to its emitter. The collector of a second output transistor is also coupled to the emitter of the first output transistor. The emitter of the second output transistor is coupled to the remaining terminal of the load. This junction is coupled through a monitor resistor to a point of reference potential. The monitor resistor monitors the current consumed by the amplifier and the voltage across it controls a third current regulator transistor which is coupled to the base of the second output transistor and controls its conductivity.
