Abstract

L'invention concerne un circuit déflecteur régulé comprenant une source d'énergie. Selon l'invention, il comporte des premier et second circuits résonnants 44 et 47 reliés à la source B+ pour en stocker de l'énergie; un circuit déflecteur 27 relié au premier circuit résonnant et en dérivant son énergie; et des premier et second moyens de commutation 46 et 49 respectivement reliés aux premier et second circuits résonnants 44 et 47 pour produire des oscillations résonnantes dans chacun des premier et second circuits résonnants, le chevauchement des angles de conduction des oscillations résonnantes contrôlant la quantité de transfert d'énergie vers le circuit déflecteur. L'invention s'applique notamment aux téléviseurs.
