Hello, I'm trying to model ZVS boost converter in OrCad using cree mosfets spice model (C3M0120090D). Everything is fine when I connect Tj and Tc nodes to a voltage sources, but I want to leave it without connection. When I uconnect this pins, I get an error: Convergence problem in Transient Analysis. I have read some posts in this forum, and in the other ones. I tried to change the VNTOL, ABSTOL, ITL1, but it doesn't work. I'm pretty new in analog schematic modelling, so please help me deal with it.
There are my schematic and mosfet spice model and simulation log file in zip.
