Abstract

Un appareil conforme à l'invention comprend notamment des moyens de génération de courant (16) qui attaquent un dispositif de commutation commandé (12) connecté à une charge (11), et des moyens de réaction (18) qui appliquent aux moyens de génération de courant un signal qui est fonction de la vitesse de variation de la tension ou du courant de la charge. L'appareil de l'invention réduit la vitesse de variation de la tension ou du courant de la charge pendant que le dispositif semiconducteur est dans sa région active, ce qui réduit le niveau des perturbations électromagnétiques.
