Power conversion apparatus

An inverter module has a first inverter driving a first electric load and a second inverter driving a second electric load, mounted on a common insulation substrate. In the first inverter, the arms of the U, V and W phases are arranged on the insulation substrate such that arms adjacent in the horizontal direction in the drawing are located displaced from each other in the vertical direction in the drawing. In the second inverter, the arms of the U, V and W phases are arranged on the insulation substrate such that arms adjacent in the horizontal direction in the drawing are displaced from each other in the vertical direction in the drawing. Moreover, the arm of the first inverter and the arm of the second inverter are arranged to be adjacent along the horizontal direction in the drawing. By such an arrangement, the in-plane temperature distribution can be rendered uniform without having to increase the area occupied by the insulation substrate.
