Abstract

La présente invention porte sur un circuit de commutation (20A) comprenant : des premiers éléments de commutation (31-33) ; des seconds éléments de commutation (41-43) ; des circuits d'attaque (24A-24F) qui commandent respectivement les éléments de commutation (31-33, 41-43) ; une première unité d'alimentation électrique (25L) qui commande les circuits d'attaque (24A -24C) ; des premiers circuits auto-élévateurs (50A, 50B) qui génèrent des tensions d'attaque destinées aux premiers éléments de commutation (32, 33) ; une seconde unité d'alimentation électrique (25H) qui commande les circuits d'attaque (24D-24F) ; et des seconds circuits auto-élévateurs (50C, 50D) qui génèrent des tensions d'attaque destinées aux seconds éléments de commutation (42, 43). Une unité de commande (13) effectue une seconde opération de mise sous tension séquentielle des premiers éléments de commutation (31, 32) avant qu'une première opération de mise sous/hors tension complémentaire des premiers éléments de commutation (31-33) et des seconds éléments de commutation (41-43) ne soit effectuée par les circuits d'attaque (24A-24F).
