Abstract

PURPOSE: To ensure a fine and wide-range control of the dynamic convergence at each part of the screen by extracting selectively the signal components of the first and second halves of one cycle from each adder circuit and then compounding these signal components to supply them to the winding of the dynamic convergence yoke.
CONSTITUTION: Adder circuit 22 and 27 compounds the sine wave voltage defining one cycle of the parabola wave voltage as its one cycle or the full-wave rectified voltage in a free amplitude control way to the parabola wave voltage featuring the cycle coinciding with the horizontal or vertical deflecting cycle. And switch circuit 35 and 38 extract the signal components of the first and second halves of one cycle from circuit 22 and 27, and these two output signal components are added 40 together. Then the extracted composite signal is supplied to the horizontal or vertical winding of the dynamic convergence yoke. In this way, a fine and wide-range control is possible for the dynamic convergence at each part of the screen.
