Multi-die temperature control device and method for controlling temperature of multi-die power module

A multi-die temperature control device that controls temperature of a multi-die power module including plural dies, the multi-die temperature control device receiving an input signal and driving independently the dies of the multi-die power module, the multi-die temperature control device comprising:

• means for obtaining within one cycle, a signal that is representative of the temperature of one die among the dies of the multi-die power module when the die is not conducting,
• means for obtaining within one period of time of the same cycle, signals that are representative of the equivalent resistor value of the internal gate resistors of all the dies in parallel in order to set a reference temperature that is dependent of the temperature of all the dies of the multi-die power module when the dies are not conducting,
• means for comparing the signal that is representative of the temperature of one die to the signal that is representative of the reference temperature,
• means for reducing the duration of the conducting time of the die or reducing the duration of the conducting time of the other dies of the multi-die power module according to the comparison result.
