Abstract (en)

[origin: ES8201789A1] A line end stage for a television receiver which comprises a transformer, a first high voltage rectifier and a second high voltage rectifier. The transformer has a primary winding coupled to the line sweep coils of the receiver, and a secondary winding. The secondary winding has one end coupled through the first high voltage rectifier to ground and through the second high voltage rectifier to the anode of the television receiver picture tube. The transformer comprises a core having a longitudinal axis. The primary winding is mounted on the core coaxial with the longitudinal axis and an insulating winding form surrounds the primary winding. The winding form is provided with spaced longitudinally-distributed radially-extending chambers and the secondary winding is located within these chambers. The thicknesses of the winding form between the bottoms of the chambers and the primary winding are greatest at the ends of the winding form and become progressively smaller toward the center of the form.

Abstract (de)

Die Erfindung betrifft den Zeilentransformator zur Erzeugung der Hochspannung in einem Fernsehempfänger. Die Hochspannungswicklung (5) besteht aus einer einzigen Wicklung ohne Anzapfungen. Ein erster Gleichrichter (6) liegt zwischen dem einen Ende der Wicklung (5) und Erde und ein zweiter Gleichrichter (7) zwischen dem anderen Ende der Wicklung (5) und der Anode der Bildröhre (9). Dadurch ergeben sich für den Hochspannungstransformator ein einfacher Aufbau und eine geringe Streuinduktivität der Hochspannungswicklung (5).
