摘要： The present invention provides an electric power converter in which a tip portion of a cooling fin on an air flow inlet side is limited to flow a large quantity of air around a connection portion, where the fin efficiency is high, of a base surface of the cooling fin and the fin so that the cooling efficiency of the cooling fin can be improved. By providing the limiting member, air or atmosphere flowing into the cooling fin is directed to flow toward the fin near the base surface. Further, by providing the limiting member, an area of a portion from which the air or atmosphere flows into the cooling fin is also limited so that the velocity of the air or atmosphere flow becomes high. By these functions and the like, the cooling efficiency of the cooling fin can be increased as compared to the prior art.

摘要： There is provided a temperature detection method of a semiconductor device that is small and low-cost and a power conversion apparatus that is small and low-cost. Temperature detection for thermal protection of a power semiconductor device is performed by a temperature detection device placed in the proximity to a component having the power semiconductor device packaged therein and in the proximity to one of an emitter terminal and a collector terminal of the power semiconductor device. As the temperature detection device can be mounted on a circuit board, it is not necessary to insulate the temperature detection device electrically from a cooling fin on which the power semiconductor device is placed and there is no need for lead wires and man-hours for wiring the lead wires. Therefore, it is possible to inexpensively realize the thermal protection of the power semiconductor device in the power conversion apparatus. It is also possible to realize miniaturization of the power conversion apparatus and reduction in assembly time.

摘要： A temperature detection method for a semiconductor device and a power conversion apparatus are disclosed. A temperature detection device is used to detect the temperature for thermal protection of a power semiconductor device. The temperature detection device is placed in the proximity of a component having the power semiconductor device packaged therein, and either an emitter terminal or a collector terminal of the power semiconductor device. Since the temperature detection device is mounted on a circuit board, it does not require insulation from a cooling fin on which the power semiconductor device is mounted and lead wires can be eliminated.
