Abstract

Convertisseur de puissance dans lequel un organe de blocage d'entrée des signaux de mise sous tension (transistor (32 ou 34)) bloque l'un des deux transistors (33, 35) et en empêche la mise sous tension aussi longtemps qu'un autre transistor se trouve sous tension, de manière à empêcher que les deux transistors (33, 35) soient mis sous tension simultanément pour court-circuiter une source de puissance à courant continu (13). Afin de détecter l'état de mise sous tension ou de mise hors tension de l'un ou de l'autre transistor, un transistor et un redresseur sont reliés en série pour former une valve à sens unique commandée. Un chemin de courant conduit un courant dans l'un des transistors pendant qu'il est sous tension dans le sens direct de la valve sans passer à travers le redresseur. Le convertisseur de puissance ci-décrit est en outre pourvu d'un moyen de détection de courant (transistor 32 ou 34). L'organe de blocage d'entrée du signal de mise sous tension est commandé par le moyen de détection de courant.
