Abstract
(DE)
Die Erfindung betrifft eine Leistungselektronik (1) für einen Elektromotor (20) eines Kraftfahrzeugantriebs, mit einer ersten Stromschiene (2), einer relativ zu der ersten Stromschiene (2) elektrisch isolierten, zweiten Stromschiene (3) und zumindest einem Kondensator (4), wobei der zumindest eine Kondensator (4) mit seiner ersten Elektrode (5) einen plattenförmigen Aufnahmebereich (6) der ersten Stromschiene (2) kontaktiert und mit seiner zweiten Elektrode (7) einen plattenförmigen Aufnahmebereich (8) der zweiten Stromschiene (3) kontaktiert, wobei zumindest eine der beiden Stromschienen (2, 3), unter unmittelbarer Ausbildung eines Kühlkanals (9a, 9b), hohl ausgebildet ist. Zudem betrifft die Erfindung einen Elektromotor (20) mit dieser Leistungselektronik (1).
(EN)
The invention relates to a power electronics system (1) for an electric motor (20) of a motor vehicle drive, comprising a first busbar (2), a second busbar (3) which is electrically insulated relative to the first busbar (2), and at least one capacitor (4), wherein the at least one capacitor (4), by way of its first electrode (5), makes contact with a plate-like receiving region (6) of the first busbar (2) and, by way of its second electrode (7), makes contact with a plate-like receiving region (8) of the second busbar (3), wherein at least one of the two busbars (2, 3) is of hollow design, with direct formation of a cooling duct (9a, 9b). The invention additionally relates to an electric motor (20) comprising this power electronics system (1).
(FR)
La présente invention concerne une électronique de puissance (1) pour un moteur électrique (20) d’une transmission d’un véhicule à moteur, pourvue d’une première barre omnibus (2), d’une seconde barre omnibus (3) isolée électriquement par rapport à la première barre omnibus (2) et au moins d’un condensateur (4) qui contacte avec sa première électrode (5) une zone de logement en forme de plaque (6) de la première barre omnibus (2) et contacte avec sa seconde électrode (7) une zone de logement en forme de plaque (8) de la seconde barre omnibus (3). Au moins une des deux barres omnibus (2, 3) est conçue de forme creuse pour la formation directe d’un canal de refroidissement (9a, 9b). La présente invention concerne en outre un moteur électrique (20) pourvu de cette électronique de puissance (1).
