Abstract
(EN)
A device configured in such a manner that a rise in the temperature of a control board is reduced and that the device is compact. The present invention is provided with: a switching element (4); a coil (9); a smoothing capacitor (10); an electrical connection member (7) for electrically connecting the switching element (4), the smoothing capacitor (10), and the coil (9); a control board (1) having a control element mounted thereon; a control signal line (5) for electrically connecting the switching element (4) and the control board (1); and a switching element installation section (6) having the switching element (4) installed thereon. The electrical connection member (7) is disposed between the switching element (4) and the control board (1). The smoothing capacitor (10) and the coil (9) are disposed on the same side as the switching element (4) with respect to the electrical connection member (7). End surfaces of the smoothing capacitor (10) and the coil (9) are located farther from the electrical connection member (7) than the surface with which the switching element (4) and the switching element installation section (6) are in contact.

L'invention porte sur un dispositif configuré de sorte qu'une élévation de la température d'un panneau de bord soit réduite et que le dispositif soit compact. La présente invention comporte : un élément de commutation (4) ; une bobine (9) ; un condensateur de lissage (10) ; un élément de connexion électrique (7) servant à connecter électriquement l'élément de commutation (4), le condensateur de lissage (10) et la bobine (9) ; un panneau de commande (1) sur lequel est monté un élément de commande ; une ligne de signal de commande (5) servant à connecter électriquement l'élément de commutation (4) et le panneau de commande (1) ; et une section d'installation d'élément de commutation (6) sur laquelle l'élément de commutation (4) est monté. L'élément de connexion électrique (7) est disposé entre l'élément de commutation (4) et le panneau de commande (1). Le condensateur de lissage (10) et la bobine (9) sont disposés du même côté que l'élément de commutation (4) par rapport à l'élément de connexion électrique (7). Les surfaces terminales du condensateur de lissage (10) et de la bobine (9) sont placées plus loin de l'élément de connexion électrique (7) que la surface avec laquelle l'élément de commutation (4) et la section d'installation d'élément de commutation (6) sont en contact.
