ABSTRACT:
A circuit for stabilizing the operating voltage across a winding of output transformer of a sweep circuit of a cathode ray tube, including a plurality of current flow paths presenting resistances which are electronically controllable and each connected between a source of operating voltage which may fluctuate in amplitude and a respective one of a plurality of taps connected along the length of the winding, and a system for varying the resistances of the paths in response to changes in the amplitude of the operating voltage in such a manner as to maintain the voltage across the entirety of the winding substantially constant. The circuit is able to utilize inexpensive components while reducing overall energy losses.
