Hello all,

I am trying to setup a simulation with the Spice model of the SiC MOSFET IMZA120R020M1H_L3 provided.

After running the simulation I get an Spice Error Log in LTSpice (see attachement)

The simulation itself is a standrad double pulse test, a screenshot is also attached.

I think there may be something wrong with the model itself because this simulation setup works fine with other SiC transistors from Wolfspeed.

I hope you can help me fix the model/simulation.

Thank you and kind regards

Hi,

Yes, you can use the model to get the desired results. we will try to rectify the errors at our end.

Hi,

Good day!

If you can share me simulation model, I will try to mimic it from my end.

Hi,

I attached my simulation model. I added IMZA120R020M1H_L3 by opening the .lib file I downloaded in LTSpice and auto generated the symbol by highlighting .SUBCKT IMZA120R020M1H_L3 in the .lib file, right click -> Create Symbol.

Kind regards

Hi,

The simulation is not stopping midway, I am getting the results. may be due to some issue in the SUBCKT model of MOSFET we are getting a popup after completing the simulation time.

Hi,

thank you for looking into it. 

Does that mean I can use the model and ignore the Spice Error? Are you guys planning to fix the problem in the model so that the error doesn't pop up?

 

Kind regards
