Abstract

Ce dispositif, plus particulièrement destiné à la protection contre les surtensions pouvant apparaître aux bornes d'un générateur de courant redressé, est du genre comprenant deux branches de circuit en parallèle dont l'une comporte une diode Zener et dont l'autre comporte un thyristor contrôlé par l'amorçage de la diode Zener. Il est prévu selon l'invention, pour le désamorçage automatique du thyristor, un circuit électronique 10 branche en parallèle avec la diode Zener 7 et le thyristor 9, et comprenant un dispositif à avalanche 18. Une borne de ce dernier est reliée à la base d'un transistor 20, dont le circuit émetteur-collecteur est en parallèle avec le thyristor 9, et l'autre borne est reliée à des moyens 11 à 17 de verrouillage et de commande et alimentation du dispositif à avalanche 18. Application aux circuits électriques des véhicules automobiles, pour la protection des accessoires.This device, more particularly intended for protection against overvoltages which may appear at the terminals of a rectified current generator, is of the type comprising two circuit branches in parallel, one of which comprises a Zener diode and the other of which comprises a thyristor. controlled by the ignition of the Zener diode. According to the invention, for the automatic deactivation of the thyristor, an electronic circuit 10 is connected in parallel with the Zener diode 7 and the thyristor 9, and comprising an avalanche device 18. A terminal of the latter is connected to the base. of a transistor 20, the emitter-collector circuit of which is in parallel with the thyristor 9, and the other terminal is connected to means 11 to 17 for locking and controlling and supplying the avalanche device 18. Application to electrical circuits motor vehicles, for the protection of accessories.
