Hello Kris, Thanks for your reply.
I have changed what you pointed out above (the 6e-15 was an error - obviously should be zero). But this does not solve my issue. It seems my error is with C3x description, because if I don’t attach any thermal description to this part my circuit runs fine. I have attached my model. The error is
Negative loss values for component 3LNPP_SiC_wo_diodes/INVERTER/FETD3.Negative switching or conduction losses are cropped
The same goes for FETD4. Looking forward to your reply.
