Abstract
La présente invention concerne l'alimentation des récepteurs de télévision. Selon l'invention, on utilise un montage redresseur en pont D1, ..., D4, un dispositif bistable Th, une résistance R1 connectée à une capacité de charge C1 par l'intermédiaire d'une lampe fluorescente à déclenchement St. Lorsque le dispositif Th est bloqué, la tension aux bornes de CI est maintenue à une valeur trop faible, pour assurer le fonctionnement du circuit de déviation horizontale. L'invention s'applique aux récepteurs de télévision.The present invention relates to the power supply of television receivers. According to the invention, use is made of a bridge rectifier assembly D1, ..., D4, a bistable device Th, a resistor R1 connected to a load capacitor C1 via a fluorescent lamp with trigger St. When the device Th is blocked, the voltage at the terminals of CI is maintained at a value too low, to ensure the operation of the horizontal deflection circuit. The invention applies to television receivers.
