Abstract

L'invention concerne un circuit amplificateur de puissance. Il comprend un préamplificateur 14, 16 destiné à amplifier un signal d'entrée, un moyen de sortie 36, 40, 38, 42 contenant un premier et un deuxième transistor montés en push-pull, un moyen de réaction 60, 66, 74, 70 qui détecte les courants du premier et du deuxième transistor et délivre un signal correspondant au préamplificateur afin d'assurer la régulation des courants d'alimentation électrique 20 connectée au moyen de sortie et produisant un niveau voulu de tension, une borne de polarisation 1 connectée au moyen de réaction et au préamplificateur et produisant, pendant une partie au moins de la période d'activité du moyen de sortie une tension supérieure à la tension voulue.
