Abstract

Circuit d'aide à la commutation de transistors de puissance. Le circuit d'aide à la commutation de transistors alimentés par une batterie d'accumulateurs et commandés par un circuit de commande à générateur de créneaux, comprend un premier condensateur en série avec une première diode connectée en parallèle sur les transistors et une première résistance en parallèle sur la première diode et est caractérisé par le fait qu'il comprend en outre une branche constituée d'un second condensateur, d'une seconde diode et d'une seconde résistance, en série, ladite branche étant en parallèle sur la première résistance. Application aux alimentations à batterie d'accumulateurs.
