Abstract
A power conversion device includes: a semiconductor module in which a semiconductor element is sealed; a drive circuit board on which a drive circuit that drives the semiconductor element is mounted; a control circuit board on which a control circuit that controls the drive circuit is mounted; and a first cooling member that cools the semiconductor module. The power conversion device is divided into a first space and a second space by a partition wall of a housing. The drive circuit board is disposed in the first space so as to face the semiconductor module with the first cooling member interposed between the drive circuit board and the semiconductor module. The control circuit board is disposed in the second space.
