Apparatus and method for controlling temperature of multi-die power module

摘要

The present invention is a method for controlling the temperature of a multi-die power module, determining a first weighted arithmetic mean of the junction temperature of the die of the multi-die power module, and storing the weighted arithmetic mean; Continuously determining another weighted arithmetic average of the die junction temperature and whether the difference between the other weighted arithmetic average and the stored weighted arithmetic average is less than a first value; If the difference between the step of determining and the other weighted arithmetic average and the stored weighted arithmetic average is less than the first value, for applying to at least one selected die of the multi-die power module If the difference between the step of allowing a change in the duty cycle of the input signal and the other weighted arithmetic average and the stored weighted arithmetic average is not less than the first value, the multi-die Comprising the input signals for application to at least one die word modules and steps to disable the change of the duty cycle, to a method.
