Abstract
(EN) An electric power conversion device which can convert a direct current electric power supplied by a direct current power source (2) into an alternate current electric power, and which comprises: six switching elements each composed of a voltage-driven transistor (6-i) (wherein i = 1, 2, …, 6) equipped with a wide band gap semiconductor and a diode (4-i); and drive circuits (5-i) that can control a voltage to be used for driving the transistor (6-i) based on a predetermined voltage profile when the switching elements are turned off, wherein the predetermined voltage profile is so determined as to drive the transistor (6-i) in a non-linear region.
(FR) L'invention concerne un dispositif de conversion d'énergie électrique qui peut convertir un courant électrique continu fourni par une source de courant électrique continu (2) en un courant électrique alternatif et qui comprend : six éléments de commutation composés chacun d'un transistor commandé en tension (6-i) (avec i = 1, 2, ..., 6) comprenant un semi-conducteur à large bande interdite et d'une diode (4-i) ; et des circuits d'attaque (5-i) qui peuvent commander une tension à utiliser pour attaquer le transistor (6-i) en fonction d'un profil de tension prédéterminé lorsque les éléments de commutation sont coupés. Le profil de tension prédéterminé est déterminé afin d'attaquer le transistor (6-i) dans une région non linéaire.
