PROBLEM TO BE SOLVED: To minimize the error of a detected temperature in the detection of the temperature of a semiconductor module consisting of a plurality of IGBT elements. SOLUTION: In this detector, temperature detecting diodes 12, 22 and 32 are provided on IGBT elements 11, 21 and 31, respectively, and the diodes 12, 22 and 32 are connected in parallel, a constant current is supplied thereto from a constant current source 40 to detect the temperature of a semiconductor module in a temperature detecting circuit 50. Resistors 13, 23 and 33 are serially connected to the temperature detecting diodes 12, 22, and 32, respectively. |
