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.
