摘要： A method for assembling semiconductor switching elements and a heat sink in a rotary electric machine includes: a first step in which bare chips of the semiconductor switching elements are bonded to the heat sink using a good heat conductive bonding material; a second step which connects the bare chips to a wiring part by wire bonding; and a third step in which a resin which seals the bare chips and the wiring part is applied to the heat sink in a striding manner in a state that output terminal portions of the wiring part and fins of the heat sink are exposed to the outside of the resin.

摘要： The present invention provides an automotive electric motor-generator that can achieve sufficient cooling of a radiating plate by ensuring a sufficient cooling airflow ventilation channel within limited axial or radial dimensions. In the present invention, first and second radiating plates each form a fan shape, have N-channel power MOSFETs mounted thereto, and have a drain potential for the power MOSFETs. A first circuit board includes insert conductors that connect the power MOSFETs in series, and a second circuit board has insert conductors that are connected to source terminals of the power MOSFETs and that have negative potential. The first radiating plate, the second radiating plate, the first circuit board, and the second circuit board are disposed in a fan shape that is centered around a shaft so as to line up radially in a plane that is perpendicular to the shaft outside one axial end of a rear housing.

摘要： An insulating sheet consisting of a metal layer and an unhardened insulating resin layer is formed. The insulating resin layer contains a filler having grains of, e.g., scale-like shape and has thixotropy, and its outer size is larger than that of a bottom surface of a metal plate. The insulating sheet is disposed on a bottom surface of a cavity of a mold die and the metal plate is disposed on an upper surface of the insulating resin layer. On a main surface of the metal plate, a power semiconductor chip connected to a frame and another frame through a wire is mounted. The cavity is fully filled with a liquid mold resin in this state. After that, the insulating resin layer is hardened at the same timing as the hardening of the mold resin, and the insulating resin and the metal plate are fixed to each other. An interface between the insulating resin layer and the metal plate is included in the upper surface of the insulating resin layer.
