Abstract
The present invention concerns a device for controlling the operation of a power module composed of switches, each switch being composed of a plurality of power dies connected in parallel, characterized in that the device comprises, for each power die of the power module: —a temperature sensor to sense the temperature of the power die, —a current sensor to sense the current going through the power die, —a gate interrupt circuit to interrupt the signal provided to the power die if the sensed current is higher than a predetermined current threshold, —a controller to reduce 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.
