Electric conversion vehicle and electric conversion vehicle

摘要

We provide a power conversion device that can reduce the number of parts in the entire system to reduce the size and improve reliability. The power conversion device (100) is a power conversion device (100) composed of a semiconductor module (110) having a half-bridge configuration in which two semiconductor elements are arranged in series. The semiconductor module (110) has a substantially rectangular shape, and is provided with a positive electrode terminal, a negative electrode terminal, an AC input / output terminal, or a terminal for a specific purpose along the longitudinal direction of the rectangular body to form a power conversion device (100). Is formed, and a plurality of semiconductor modules (110) are arranged vertically side by side in the vertical direction, which is the lateral direction of the rectangular body, to form a plurality of phases constituting the power conversion device (100). The multi-phase semiconductor module (100) is installed in contact with the cooler (150), and one or more capacitors (120) are arranged opposite the cooler (150) with the multi-phase semiconductor module (110) in between. Will be done.
