Abstract
(EN)
Circuit inductance between smoothing capacitors connected to connection conductors for positive and negative electrodes, and semiconductor power modules which form inverters, increases in accordance with current imbalance in the circuit loop. Arms of each phase which connect the semiconductor power modules in series are in a state of overlapping each other, and are arranged in the same direction as the semiconductor power modules connected to the connection conductors for the positive electrodes, and the semiconductor power modules connected to the connection conductors for the negative electrodes. Gaps are provided between the arranged electrodes of the semiconductor power modules. In these gaps, the connection conductors for the positive and negative electrodes are provided in a parallel state with an insulation member therebetween. The connection conductors are bent in the vicinity of connection terminals of the semiconductor power modules to attach the semiconductor power modules.

Selon l’invention, l’inductance de circuit entre des condensateurs de lissage, connectés à des conducteurs de connexion pour des électrodes positive et négative, et des modules de puissance semi-conducteurs qui forment des onduleurs Les bras de chaque phase qui connectent les modules de puissance semi-conducteurs en série se trouvent dans un état de superposition des uns par rapport aux autres, et sont agencés dans la même direction que les modules de puissance semi-conducteurs connectés aux conducteurs de connexion pour l’électrode positive, et les modules de puissance semi-conducteurs connectés aux conducteurs de connexion pour l’électrode négative. Des espaces sont ménagés entre les électrodes agencées des modules de puissance semi-conducteurs. Dans ces espaces, les conducteurs de connexion pour les électrodes positive et négative sont disposés dans un état parallèle, un organe d’isolation étant intercalé. Les conducteurs de connexion sont courbés au voisinage de bornes de connexion des modules de puissance semi-conducteurs pour fixer les modules de puissance semi-conducteurs.
