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.
