Abstract
A method for predicting a temperature of a heat sink for cooling a power module including at least one switching element and a Negative Temperature Coefficient of Resistance (NTC) sensor is provided. The method for predicting a temperature of a heat sink includes: estimating a temperature variation of the NTC sensor using a power loss of the power module based on a power loss occurring in the at least one switching element according to driving of the power module and a thermal resistance of the power module; obtaining a temperature of the power module detected by the NTC sensor; and predicting the temperature of the heat sink from a difference between the temperature of the power module and the temperature variation of the NTC sensor.
