Abstract

Dans un montage, où lorsque l'amplitude de la tension alternative croît, la conductance d'un premier circuit augmente et lorsque l'amplitude de la tension alternative décroît rapidement, la conductance d'un second circuit augmente, on prévoit un circuit de retard disposé dans le trajet de commande pour le second circuit La conductance du second circuit est commandée en fonction de la différence entre les durées respectives de la croissance et de la décroissance rapide de l'amplitude de la tension alternative.
