Title: (DE) STROMRICHTER
(EN) POWER CONVERSION APPARATUS
(FR) APPAREIL DE CONVERSION DE PUISSANCE
Abstract: front page image
(EN) An electric power converter is provided with: a power semiconductor module, which has a power semiconductor element that converts a direct current into an alternating current; a capacitor module, which has a capacitor element that smooths the direct current; and a cooling body, which cools the power semiconductor module and the capacitor module. The capacitor module has: a case, which has an approximately rectangular shape, has an opening formed in one surface, and has a space for housing the capacitor element; and a DC conductor for electrically connecting the power semiconductor element and the capacitor element to each other. The cooling body is formed to face the bottom surface on the inner wall of the case, and both the side surfaces of the case, the side surfaces facing each other. Between the capacitor element and the inner wall surfaces of the case, the direct current conductor is formed along the bottom surface and both the side surfaces of the case.
(FR) L'invention concerne un appareil de conversion de puissance qui comporte : un module à semi-conducteur de puissance, qui comporte un élément semi-conducteur de puissance qui convertit de l'électricité en courant continu en de l'électricité en courant alternatif ; un module à condensateur, qui possède un élément condensateur qui lisse l'électricité en courant continu ; et un corps de refroidissement qui refroidit le module à semi-conducteur de puissance et le module à condensateur. Le module à condensateur comporte : un boîtier, qui présente une forme sensiblement rectangulaire, présente une ouverture formée dans une surface et présente un espace destiné à recevoir l'élément condensateur ; et un conducteur à courant continu destiné à connecter électriquement l'élément semi-conducteur de puissance et l'élément condensateur l'un à l'autre. Le corps de refroidissement est formé de façon à être tourné vers la surface inférieure sur la paroi interne du boîtier et les deux surfaces latérales du boîtier, lesdites surfaces latérales étant tournées l'une vers l'autre. Entre l'élément condensateur et les surfaces de paroi interne du boîtier, le conducteur de courant continu est formé le long de la surface inférieure et des deux surfaces latérales du boîtier.
