Abstract

L'INVENTION CONCERNE UN CIRCUIT DE COMMUTATION A TRANSISTORS. CE CIRCUIT COMPORTE UN TRANSISTOR DE SORTIE QUI EST AMENE A SATURATION AFIN DE PASSER RAPIDEMENT A L'ETAT PASSANT, ET QUI EST MAINTENU A L'ETAT SATURE PENDANT UNE PARTIE IMPORTANTE DE SON TEMPS DE CONDUCTION, AFIN DE CONSOMMER UN MINIMUM DE PUISSANCE. PEU DE TEMPS AVANT LE PASSAGE DU TRANSISTOR DE SORTIE A L'ETAT BLOQUE, UNE DIODE EST CONNECTEE ENTRE LA BASE ET LE COLLECTEUR DE CE TRANSISTOR, AFIN DE DERIVER UNE CERTAINE PARTIE DU COURANT DE BASE POUR QUE LE TRANSISTOR NE SOIT PLUS A L'ETAT SATURE, CE QUI PERMET D'ACCELERER LE PASSAGE A L'ETAT BLOQUE. DOMAINE D'APPLICATION : CIRCUITS DE COMMUTATION A TRANSISTORS DE PUISSANCE.
