摘要： An Inverter-integrated rotating electrical machine includes: a rotating electrical machine including a rotor and a stator; a housing member forming a housing chamber that houses the rotating electrical machine; a cover member that covers an opening on one end side of the housing member in an axial direction and that includes a support portion rotatably supporting the rotor; a power switching element located between the cover member and the rotating electrical machine in the axial direction; and a smoothing capacitor located between the cover member and the rotating electrical machine in the axial direction. The cover member includes a cooler that cools the power switching element and the smoothing capacitor. The power switching element and the smoothing capacitor are connected to the cover member in a thermally conductive manner.

摘要： Disclosed is a switching element module including a first switching element and a second switching element connected between a positive electrode and a negative electrode of a direct current power supply, a smoothing capacitor connected between the positive electrode and the negative electrode of the direct current power supply, and a cooling block thermally connected to a cooler. The first switching element is fixed to one side face of the cooling block. The second switching element is fixed to the other side face of the cooling block. The smoothing capacitor is fixed to a positive terminal of the first switching element and a negative terminal of the second switching element, and is provided to face a first connection surface of the cooling block that connects the one side face and the other side face.
