A control device which comprises a three-phase inverter that drives a motor, and which is provided with a circuit board and a plurality of power elements that are mounted on the circuit board and constitute the three-phase inverter. This control device comprises: a first power element which is mounted on a first mounting surface of the circuit board, said first mounting surface being on one side of the circuit board; a second power element which is mounted on a second mounting surface that is on the reverse side of the first mounting surface; and a heat sink which is thermally in contact withthe first power element and the second power element. This control device has an element pair that is composed of the first power element and the second power element, which are mounted in positions where the power elements overlap with each other at least partially when viewed from a direction that is perpendicular to the plane direction of the circuit board.

    一种控制装置,其包含驱动马达的三相逆变器,其中,该控制装置具有:电路板;以及多个功率元件,它们安装于电路板,构成三相逆变器,该控制装置具有:第1功率元件,其安装于电路板的一侧的第1安装面;第2功率元件,其安装于与第1安装面为相反侧的第2安装面;以及散热器,其与第1功率元件和第2功率元件热接触,该控制装置具有由第1功率元件和第2功率元件构成的元件对,沿与电路板的平面方向垂直的方向观察时,构成该元件对的该第1功率元件和该第2功率元件安装在至少一部分重叠的位置。
