Abstract

Système d’interrupteurs et convertisseur de tension comportant un tel système d’interrupteur L’invention concerne système d’interrupteur (10) comprenant : un interrupteur (Q3) comportant une borne d’entrée de courant (D3), une borne de sortie de courant (S3) et une borne de commande (G3) destinée à recevoir une tension de commande (Vgs3) pour sélectivement ouvrir et fermer ledit interrupteur (Q3), une première résistance (Ra) connectée à la borne de commande (G3) et à la borne de sortie de courant (S3) de l’interrupteur (Q3), un dispositif de commande (30) dudit interrupteur (Q3) destiné à être connectée à une source de tension continue (Vcc), ladite source de tension continue (Vcc) étant référencé par rapport à la borne de sortie de courant (S3) du troisième interrupteur (Q3), caractérisé en ce que ledit système d’interrupteur (10) comprend en outre un dipôle (40), ledit dipôle (40) est connecté par une de ses deux bornes à ladite borne de commande (G3) et par l’autre de ses deux bornes audit dispositif de commande (30), ledit dipôle (40) comprend une capacité (Ccf) et une deuxième résistance (Rcf) connectés en parallèle entre les deux bornes du dipôle (40) et en ce que ledit dispositif de commande (30) est conçu pour connecter la source de tension continue (Vcc) à la borne de commande (G3) de l’interrupteur (Q3) par l’intermédiaire dudit dipôle (40) afin de commander à la fermeture l’interrupteur (Q3). Figure pour l’abrégé : Figure 2Switch system and voltage converter comprising such a switch system The invention relates to a switch system (10) comprising: a switch (Q3) comprising a current input terminal (D3), a current output terminal current (S3) and a control terminal (G3) intended to receive a control voltage (Vgs3) to selectively open and close said switch (Q3), a first resistor (Ra) connected to the control terminal (G3) and to the current output terminal (S3) of the switch (Q3), a control device (30) of said switch (Q3) intended to be connected to a DC voltage source (Vcc), said DC voltage source (Vcc ) being referenced with respect to the current output terminal (S3) of the third switch (Q3), characterized in that said switch system (10) further comprises a dipole (40), said dipole (40) is connected by one of its two terminals to said control terminal (G3) and by the other to s between the two terminals of said control device (30), said dipole (40) comprises a capacitor (Ccf) and a second resistor (Rcf) connected in parallel between the two terminals of the dipole (40) and in that said control device ( 30) is designed to connect the DC voltage source (Vcc) to the control terminal (G3) of the switch (Q3) via said dipole (40) in order to command the switch (Q3) to close .
