Abstract

Dispositif pour protéger les semi-conducteurs de puissance contre les amorçages gâchette en l'air. Un condensateur C et au besoin une résistance R sont montés entre un point de raccordement A, situé en amont du semi-conducteur de puissance Tc dans le sens du passage du courant, du circuit de courant de charge, et la gâchette S du semi-conducteur de puissance.
