This paper will summarize the approaches and applications of temperature sensor for IGBT modules, including direct measurement of mounting a sensor on the chip and the NTC inside IGBT modules. Additionally, the calculation methods of the maximum junction temperature Tjmax for low output frequencies are introduced. This paper will also show how to design temperature sensing circuit and set over-temperature protection for Mitsubishi CM450DX-24S1.
