Classification: CPC G  H | IPC G  H

Claim 6:
7. A measurement method for estimating a temperature of a power semi-conductor module according to claim 1;
said method comprising:
a) trigger a measurement when no current is provided from the Emitter E of the Insulated Gate Bipolar Transistor IGBT, respectively from the Source S of the Metal-Oxide-Semiconductor Field-Effect Transistor MOSFET;
b) generate a diagnostic mode of the first electrode of the module during which a resistance is positioned in a closed electrical network including the first electrode, the second electrode, and a voltage source of a gate driver;
c) monitor at least a voltage or a current on said loop;
d) convert the monitored values into temperatures according to calibration data.
