Abstract

Method to control a power semiconductor module comprising: a. monitoring at least one operating parameter, b. only if said operating parameter is kept into a range and said operating parameter's range has an initial status, initiate a calibration stage, said calibration stage including i. measuring a first temperature sensitive electrical parameter; ii. decreasing the dead-time; iii. monitoring said operating parameter; iv. measuring a second temperature sensitive electrical parameter; v. only if - said operating parameter has been kept into said range and - the value of the second temperature sensitive electrical parameter corresponds to a lower value of the temperature, assigning the value of the dead-time; else only if - said operating parameter has been kept into said range and - the value of the second temperature sensitive electrical parameter corresponds to a higher value of the temperature, updating the status, vi. storing the dead-time with said operating parameter's range.
