Abstract
(EN)
The purpose of the present invention is to provide a power conversion device capable of reducing noise that occurs when increasing the temperature of a storage battery is controlled. This power conversion device (10) is provided with: a rotary electric machine (40) having windings (41U, 41V, 41W, 41X, 41Y); an inverter (30) having a serial connector of upper arm switches (QUH, QVH, QWH, QXH, QYH) and lower arm switches (QUL, QVL, QWL, QXL, QYL); and a capacitor (31) connected in parallel to the serial connector. The power conversion device is further provided with: connection paths (60, 90, 90U, 90W) which, in a first storage battery (21) and a second storage battery (22) connected in series, electrically connect the windings and the negative electrode side of the first storage battery and the positive electrode side of the second storage battery; and a control unit (70) which controls switching of the upper arm switches and the lower arm switches such that current flows between the first storage battery and the second storage battery via the inverter, the windings, and the connection paths.

L’objet de la présente invention est de mettre en œuvre un dispositif de conversion de puissance pouvant réduire le bruit qui se produit lorsque l’accroissement de la température d’une batterie d’accumulateurs est contrôlé. Ce dispositif de conversion de puissance (10) comporte : une machine électrique rotative (40) ayant des enroulements (41U, 41V, 41W, 41X, 41Y) ; un onduleur (30) ayant un connecteur en série de commutateurs de bras supérieur (QUH, QVH, QWH, QXH, QYH) et de commutateurs de bras inférieur (QUL, QVL, QWL, QXL, QYL) ; et un condensateur (31) connecté en parallèle au connecteur en série. Le dispositif de conversion de puissance comporte en outre : des chemins de connexion (60, 90, 90U, 90W) qui, dans une première batterie d’accumulateurs (21) et une deuxième batterie d’accumulateurs (22) connectées en série, connectent électriquement les enroulements et le côté de l’électrode négative de la première batterie d’accumulateurs et le côté de l’électrode positive de la deuxième batterie d’accumulateurs ; et une unité de commande (70) qui commande la commutation des commutateurs de bras supérieur et des commutateurs de bras inférieur de sorte que le courant circule entre la première batterie d’accumulateurs et la deuxième batterie d’accumulateurs par le biais de l’onduleur, des enroulements, et des chemins de connexion.
