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.
