Title (EN) VOLTAGE CONVERTER ON BOARD A MOTOR VEHICLE AND ASSOCIATED ELECTRIC CHARGER
(FR) CONVERTISSEUR DE TENSION EMBARQUE SUR UN VÉHICULE AUTOMOBILE ET CHARGEUR ÉLECTRIQUE ASSOCIE
Abstract:
(EN) The invention relates to a voltage converter (200) on board a motor vehicle, for converting a first voltage into a second voltage different from the first voltage, comprising: - a plurality of cells (C), each comprising an arm of transistors (T3, T4) controlled as a chopper to generate the second voltage; - at least one isolation transistor (K3-R); and - a circuit (210) for controlling the transistors, the control circuit (210) being configured to be able to selectively keep said at least one isolation transistor (K3-R) open so as to decouple a cell of the plurality of cells and to use the arm (K5, K6) of said cell to supply a third output voltage.
(FR) L'invention concerne un convertisseur (200) de tension embarqué sur un véhicule automobile, pour convertir une première tension en une deuxième tension différente de la première, comportant : - une pluralité de cellules (C), comportant chacune un bras de transistors (T3, T4) commandé en hacheur pour générer la deuxième tension, - au moins un transistor d'isolement (K3-R), et - un circuit de contrôle (210) des transistors, le circuit de contrôle (210) étant configuré pour pouvoir sélectivement maintenir ouvert ledit au moins un transistor d'isolement (K3-R) afin de découpler une cellule de la pluralité de cellule et d'utiliser le bras (K5, K6) de ladite cellule pour fournir une troisième tension de sortie.
