Patent attributes
In a power conversion device, each of semiconductor modules of a layered body includes a body portion incorporating a plurality of switching elements and a plurality of power terminals protruding therefrom. The semiconductor modules include upper-arm switching elements and lower-arm switching element that are alternately layered in a layering direction of the layered body. A capacitor is disposed on one side of the layered body and a current sensor is disposed on an opposite side of the layered body, in an orthogonal direction orthogonal to both a protruding direction of the power terminals and the layering direction. Each of the semiconductor modules includes, as the power terminals, two collector terminals connected to a collector electrode of the switching element and one emitter terminal connected to an emitter electrode of the switching element, and the emitter terminal is disposed between the two collector terminals in the orthogonal direction.
