Dear Engineers & Infineon!

I am Tung, who currently work on OBC projects, I would like to use Infineon-IMZ120R030M1H device as SiC power switches. Before using it, I would like to model this device instead of using the model from Infineon. However, I am not sure how to determine the lead inductance for D,G,S, SSense pins of SiC packages from Spice model?

I am able to find some inductaces values inside the Spice model. But the problem is they use L1,L2,L3 and L4 for lead inductances, I am not sure which inductances belongs to which pins. Would you mind to give me some suggestions on this issue?

Thank you!

Dear  

If you need to recreate the model by yourself, then after the modification you can validate the model according to the characteristic curves in the datasheet.

Best regards,

Rachel

Dear @Rachel_G 

Thank you for your answer! Actually, the Spice model is good but it also a computational burden model. So that I just want to build a simpler model for PSIM simulation. Is there any way for me to solve this problem? Great thanks!
