Abstract

An electronic beam convergence apparatus for a television color image display system that includes a multiple beam color image reproducing device and the biasing means for biasing said beams into a series of horizontal lines spaced vertically during periods successive beam tracing in order to form a raster, the combination for said beams to converge at all points of said raster consisting of: at least one dynamic convergence electromagnet provided with an activation winding; and a sawtooth wave source; characterized by means including a transistor coupling said source with said winding, to impress said sawtooth wave on said winding only during the last half of each of said tracing periods in order to store energy in said winding; and a wave forming circuit connected through said winding in order to effect a substantially parabolic current flow through said winding without substantially any current flow in the middle of each of said stroke periods.
