Power Conversion Device

摘要

A power conversion device capable of reducing a temperature variation between a plurality of semiconductor modules is provided. The power conversion device comprises condensers 121, 122, a plurality of semiconductor modules 101, 102, heat dissipation units 103 to 109, a bus bar 140 connecting the condensers 121, 122 with the plurality of the semiconductor modules 101, 102, and a ventilation unit having cool wind blow. The power conversion module has features that the plurality of semiconductor modules 101, 102 are arranged apart from the condensers 121, 122 and in a line in a longitudinal direction of the bus bar 140 and that the cool wind 150 blows in a direction from the condensers 121, 122 toward the plurality of semiconductor modules 101, 102 that are mounted.
