Spice Models for XM3 modules

luke13

Hello Wolfspeed Technicians,

I'm currently writing my bachelor thesis about an inverter with SiC power modules. I would like to compare your XM3 modules in ltspice.

Would it be possible to get a spice model for CAB400M12XM3 and CAB425M12XM3?

I already got the one for CAB450M12XM3 from this discussion (https://forum.wolfspeed.com/discussion/465/cab450m12xm3-ltspice-model).

And looks like you already created one for the CAB400M12XM3 here https://forum.wolfspeed.com/discussion/425/help-with-modelling-cab400m12xm3.

Thanks in advance.

Best regards Lukas

All SPICE models can now be found on our website at https://www.wolfspeed.com/tools-and-support/power/ltspice-and-plecs-models/

Hi Luke,

Since you will be using LTSpice specifically, you can use our new library file (attached) for the XM3 SPICE models. There have been many improvements since those previous forum posts. There is some information in the header of the .lib file to help get you started.

To change the module being simulated, right-click the symbol and type in the model name in the 'value' field. You can also control some model complexity in the SpiceLine fields (this is described in the text header). For inverter circuits that have multiple modules, it may be prudent to specify these parameters as variables from .param statements. Also, please ensure that you have the latest version of LTspice 17.1 installed (not XVII).

Please let me know if you have any feedback or questions, and remember that these models are still preliminary.

Thanks,

Brian
