Abstract

The present invention concerns a device (102) for controlling the operation of a power module (150) composed of switches, each switch being composed of a plurality of power dies (305) connected in parallel, wherein the device comprises, for each power die of the power module: - means (303) for sensing the temperature of the power die (305), - means (304) for sensing the current going through the power die (305), - means (312) for gating the signal provided to the power die if the sensed current is higher than a predetermined current threshold,- means for reducing the conducting time of the die if the sensed temperature of the power die is higher than the average die temperature across the power dies of at least one switch.
