Device and method for controlling operation of power module composed of switches

A device for controlling the operation of a multi-die power module composed of a plurality of power dies connected in parallel, comprising:

• a plurality of controllers, one for each of the plurality of power dies, configured to control operation of a respective one of the plurality of power dies;
• wherein each of the plurality of controllers includes a temperature sensor to sense the temperature of the respective power die;
• and
• a host controller configured to
• obtain information representative of a temperature of each of the plurality of power dies and calculate an average temperature of the plurality of power dies;
• compare, for each of the plurality of power dies, the respective temperature of an individual power die to the average temperature;
• and
• reduce the conducting time of a respective power die if the temperature of the respective power die is higher than the average temperature across the plurality of power dies.
