Abstract
A saturable reactor having a pair of series coils is attached to the outside surface of the cores of the vertical deflecting coils where the series coils are connected in series with a parallel connection of the horizontal deflecting coils. Each of the pair of coils of the saturable reactor is wound around a drum core which is magnetically biased by means of a permanent magnet. The saturable reactor is positioned so that leakage flux from the vertical deflecting coils is led into the drum cores, thereby changing the inductance of the pair of coils in accordance with the degree of vertical deflection. The horizontal deflecting currents flowing through the horizontal deflecting coils thus controlled to chage the width of raster providing a trapezoidal raster which is needed for projecting a TV picture on a large screen.
