Abstract
Circuit de Darlington à paire de transistors avec un transistor de puissance haute tension pour un circuit de déviation de ligne et/ou un circuit de tension d'alimentation à découpage. Le circuit de commande comporte deux voies de courant, à savoir une voie de courant d'enclenchement (état conducteur) contenant une source de courant commuté et couplée à la base du transistor de puissance haute tension et une voie de courant de déclenchement (état non conducteur) qui comporte une inductance, une source de tension pratiquement constante, ainsi qu'un interrupteur, et qui est incorporée entre la base et l'émetteur du transistor de puissance haute tension, le courant commuté passant lorsque interrupteur est ouvert et ne passant pas lorsqu il est fermé. Application : récepteurs de télévision.
