Abstract
A semiconductor chip temperature estimation device that estimates the temperature of a semiconductor chip incorporated together with a thermistor in a semiconductor module includes a first estimation unit which calculates a first estimation value of a chip loss of the chip, a memory which stores in advance a correlation between a temperature rise of the temperature sensor and the chip loss of the chip, a second estimation unit which calculates a second estimation value of the temperature rise of the temperature sensor, and a third estimation unit which calculates a third estimation value of the temperature of the cooling element. The temperature of the semiconductor chip is estimated by using the third estimation value as a base temperature.
