Abstract: The power conversion device includes a plurality of semiconductor modules, each having a main body section including a switching element therein. In a module unit, a positive module and a negative module are disposed such that main surfaces of the respective main body sections oppose each other. A positive terminal, a first intermediate terminal, a negative terminal, and a second intermediate terminal project in a Z direction perpendicular to X direction in which the positive module and the negative module oppose each other. A first vector V1 from the positive terminal towards the first intermediate terminal and a second vector V2 from the second intermediate terminal towards the negative terminal are configured such that these vector components V12 and V22 in a Y direction perpendicular are opposite to each other.

Abstract: A power conversion device includes an electronic component, a cooler, a housing, protruding pipes, and annular seal members. Each of the seal members includes a seal body portion interposed between a corresponding one of the protruding pipes and the housing, and a flange portion extending outward from the seal body portion in a radial direction and contacting an outer surface of the housing from an axial direction. The housing includes a peripheral wall surface formed to surround the flange portion from an outer peripheral side, and an annular groove portion formed along an outer peripheral edge of the flange portion inside the peripheral wall surface. The peripheral wall surface is formed to extend outward, in the axial direction, from an axial contact surface of the housing contacted by the flange portion.

Abstract: A power converter is equipped with a semiconductor module stack, a positive bus bar stack, and a negative bus bar stack. The positive bus bar stack has a first positive bus bar and a second positive bus bar stacked. The negative bus bar stack also has a first negative bus bar and a second negative bus bar stacked in a stacking direction Z of the positive bus bar stack. The first semiconductor modules of the semiconductor module stack are connected to the first positive bus bar and the first negative bus bar, while the second semiconductor modules of the semiconductor module stack are connected to the second positive bus bar and the second negative bus bar. This results in a decreased variation in mutual inductance among the semiconductor modules, which leads to a decrease in overall inductance of the power converter.
