Abstract

L’invention concerne un système de conversion électrique destiné à être connecté à une batterie (BATT), par exemple d'un véhicule électrique ou hybride pour convertir la tension d'entrée fournie par la batterie en une tension auxiliaire (V_aux). Le système comporte une unité de conversion (2) dotée de deux convertisseurs électriques (U1, U2), un premier convertisseur (U1) apte à être commandé pour générer la tension auxiliaire (V_aux) et pour fournir une première puissance électrique, et un deuxième convertisseur (U2) également apte à être commandé pour générer ladite tension auxiliaire (V_aux) et pour fournir une deuxième puissance électrique ayant une valeur plus élevée que celle de la première puissance électrique fournie par le premier convertisseur électrique. Un circuit analogique de pilotage est employé pour activer le deuxième convertisseur électrique (U2) lorsqu'un surplus de puissance est nécessaire, notamment au démarrage du véhicule. Figure à publier avec l'abrégé : Figure 1The invention relates to an electrical conversion system intended to be connected to a battery (BATT), for example of an electric or hybrid vehicle to convert the input voltage supplied by the battery into an auxiliary voltage (V_aux). The system comprises a conversion unit (2) provided with two electrical converters (U1, U2), a first converter (U1) capable of being controlled to generate the auxiliary voltage (V_aux) and to provide a first electrical power, and a second converter (U2) also able to be controlled to generate said auxiliary voltage (V_aux) and to provide a second electrical power having a value higher than that of the first electrical power supplied by the first electrical converter. An analog control circuit is used to activate the second electrical converter (U2) when additional power is necessary, particularly when starting the vehicle.
