Abstract

1. A circuit arrangement for the vertical deflection of electron beams in a television picture tube, wherein the deflection current is obtained by actuating, with line-frequency, pulse-width-modulated signals, a bipolar switch (2, 3), one contact of which is directly at reference potential and the other contact of which is connected to reference potential through a series connection consisting of a winding (8) of the line transformer, of an integrating coil (4) and of an integrating capacitor (5), one connection of the deflection winding (6) of the television picture tube being connected to a positive supply voltage (+) through a precision resistor (7), characterised in that an inductive component (4', 9) is connected in series with the integrating capacitor (5) and that the other connection of the deflection winding (6) of the television picture tube is connected to the reference potential through the series connection of the inductive component (4', 9) and the integrating capacitor (5), the inductive component being so dimensioned that it at least compensates the current through the deflection winding (6) resulting from the line-frequency residual voltage at the integrating capacitor (5).
