Abstract: In a power conversion device, first-phase semiconductor modules are successively arranged in a first direction to form a part of a first row. Second-phase semiconductor modules are successively arranged in the first direction to form a part of a second row while facing the first-phase semiconductor modules. Third-phase semiconductor modules are arranged in a second direction so that one of the third-phase semiconductor modules forms a part of the first row and another of the third-phase semiconductor modules forms a part of the second row. The first row and the second row have surfaces facing each other and from which output terminals protrude. Each of output conductors extends from a connected portion of an output terminal in a direction away from the third-phase semiconductor modules.

Abstract: A rotating electric machine includes a housing member including a cylindrical portion. First and second electrical components are arranged in the circumferential direction along the cylindrical portion in a radial direction of the cylindrical portion. A coolant passage between an inlet portion and an outlet portion is formed in the cylindrical portion. The housing member includes a partition wall portion partitioning a portion of the coolant passage from the inlet portion to a specific position between the inlet portion and the outlet portion in the circumferential direction as an upstream-side path. The partition wall portion is separated in the radial direction from a wall portion of the cylindrical portion. The first electrical component is arranged on an inner side in the radial direction relative to the upstream-side path, and the second electrical component is arranged on the inner side in the radial direction relative to a downstream-side path.
