Abstract

L'invention concerne un convertisseur de blocage, notamment pour des appareils à flash alimentés par des accumulateurs ou par des piles. Dans ce convertisseur de blocage comportant un transistor de commutation T, un transformateur Tr, un circuit de commande S, la commande du transistor T s'effectue au moyen d'une bascule monostable dont le temps de branchement est réglé par un organe RC et il est prévu un circuit de déclenchement de la bascule monostable provoquant le déclenchement dès que l'énergie stockée dans le transformateur Tr est déchargée dans le condensateur de charge CL , ainsi qu'un capteur RF qui mesure une grandeur Upr , U sek , isek caractéristique pour l'énergie stockée dans le transformateur, pendant la phase de blocage du transistor T. Application notamment aux appareils électroniques à flash alimentés par piles.
