Abstract

The present invention concerns a method for controlling the operation of a multi-die power module composed of at least two dies connected in parallel. The method comprises the steps of: - obtaining the current flowing in the multi-die power module, - obtaining a loss profile that is related to the dies of the multi-die power module, - estimating from the measured current flowing in the multi-die power module, the losses of one die when no die is passivated, when the die is passivated, and when at least one other die is passivated, - determining if and which die has to be passivated from the estimated losses and from the loss profile - passivating the die which has to be passivated if a die has to be passivated.
