Abstract

L'invention concerne un circuit de balayage dans lequel la régulation de l'alimentation est réalisée à un coût très bas et avec un excellent rendement. Selon l'invention, le commutateur d'entrée T1, qui applique la tension d'alimentation non régulée au circuit de balayage, est rendu conducteur pendant un temps qui dépend des variations d'amplitude de ladite tension d'alimentation. L'invention s'applique aux récepteurs de télévision.
