Abstract
A power conversion unit includes a plurality of semiconductor modules, a gate drive circuit, a first substrate having a flat plate shape, and a second substrate having a flat plate shape. The first substrate has a first surface facing a bottom plate of a casing accommodating the semiconductor modules and the gate drive circuit, and a second surface on an opposite side to the first surface. The second substrate is arranged above the first substrate in parallel with the second surface. The semiconductor modules are mounted on the first surface. The gate drive circuit is formed on a surface of the second substrate on a side that does not face the second surface. The power conversion unit further includes a connector provided on the second surface and connected to a surface on a side facing the second substrate.
