Abstract:
The present invention provides a vehicle power module and a power converter including a power semiconductor element (328), a plurality of connecting conductors (371U, 372U, 373U) for transmitting current to the power semiconductor element (328), and a metallic base (304) upon which the power semiconductor element (328) and the plurality of connecting conductors (371U, 372U, and 373U) are mounted; and the power semiconductor element (328) and the plurality of connecting conductors (371U, 372U, and 373U) are mounted upon the metallic base (304) so as to form a looped current path. Desirably, the power semiconductor element (328) and the plurality of connecting conductors (371U, 372U, 373U) are arranged so as to form two or more looped current paths.
