Devices and methods for controlling the temperature of multi-die power modules

摘要

The present invention concerns a method for controlling the temperature of a multi-die power module, the method comprising the steps of: - determining a first weighted arithmetic mean of junction temperatures of the dies of the multi-die power module and memorizing the weighted arithmetic mean, - determining successively another weighted arithmetic mean of junction temperatures of the dies, - checking if the difference between the other weighted arithmetic mean and the memorized weighted arithmetic mean is lower than a first predetermined value, - enabling a modification of the duty cycle of an input signal to apply to at least one selected die of the multi-die power module if the difference between the other weighted arithmetic mean and the memorized weighted arithmetic mean is lower than a first predetermined value, - disabling a modification of the duty cycle of the input signal to apply to the at least one die of the multi-die power module if the difference between the other weighted arithmetic mean and the memorized weighted arithmetic mean is not lower than the first predetermined value.
