High voltage transformer graded technology, in particular for a trichromatic cathode tube

摘要

In order to obtain a dc voltage of the focusing free of undulation on a high voltage transformer technology, it is taken not at the midpoint of the second section of the secondary winding 3a, but at a point determined by the ratio of the stray capacitances of the two half - windings of this section, and it is directly connects a high value resistor 16. & br / (see appended drawing in bopi) & br / & & br /
