How to set the Rise time and Fall time of the MOSFET di/dt model

1

Hello.

I’m trying to apply di/dt model (MOSFET) for the inverter simulation.
So I checked the datasheet of the FET(PGA26E07BA) and Rise time and Fall time.
Rise time (tr) : 5.6 ns, Fall time (tf) : 2.4 ns
(under the VDD = 400 V, IDS = 8 A)

I set this condition on the PLECS, but the Rise time and Fall time didn’t match.
How can I set the Rise and Fall times accurately?

Hello,

The screenshots are helpful, but it is much easier to give feedback if you attach your model. Anyway, please see the help description for the “IGBT with Limited di/dt” component as there are example plots showing you what the rise and fall times are graphically. This should help you to verify that the model is correct.

Thank you,

Kris
