CAB011M12FM3 SpeedFit switching loss predictions

Matt

I have been using the excellent SpeedFit simulation tool to assess the most suitable module rating for a DC/AC inverter application. I am a little confused by the results for the CAB011M12FM3 device...maybe the model has been adjusted recently?

Predicted switching losses for the CAB011M12FM3 device are higher than the smaller CAB016M12FM3 device (as expected), but confusingly also higher than the larger CAB008M12GM3. The switching losses for the CAB011M12FM3 seem to have increased from results obtained earlier in the year (was circa 365W in April, now 525W under the same conditions).
