Abstract

The present invention concerns a method and a system for increasing the lifetime of at least two power dies or power modules. The invention:- senses the temperature of the power dies or the power modules,- identifies, for each power die or power module, temperature cycles from the sensed temperatures,- determines, for each power die or power module, reliability parameters from the identified temperature cycles,- determines, for each power die or power module, reference temperatures,- subtracts, for each power die or power module, the sensed temperature of the power die or power module from the determined reference temperature of the power die or power module,- adjusts the duration of the conducting time and/or the switching delay of at least one power die or power module according to the sign of the output of the subtraction.
