Abstract

This invention is based on the fact that the threshold voltage of power insulated gate bipolar transistors linearly decreases with an increase of silicon temperature. Threshold voltage according to this invention is determined through voltage detection between the control and power connections of the transistor emitter. Silicon temperature is determined from the threshold voltage measured in such a way on the basis of the predetermined linear threshold voltage temperature dependency on the silicon temperature for a certain transistor. The measured threshold voltage is used for designing over-temperature protection and for measuring silicon temperature in real time in operational conditions. Fig. 2 shows a block diagram of the device (1) for measuring silicon temperature and over-temperature protection of power insulated gate bipolar transistor (20). The device (1) consists of a circuit (2) for voltage detection between the control and power connections of the transistor emitter, circuit (3) for over- temperature protection and measuring silicon temperature and circuit (4) for turning transistor 20 on and off.
