I am trying to simulate the programmable dead time of the UCC21530 SiC gate driver on PSPICE.
When I simulate the driver I get the following error:
ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U1.V_V13. You may break the loop by adding a series resistance
I tried to add a resistor t pin 13 as the error suggested but that didn't work.
Is it A design flaw, or a model flaw? Does anyone know how to fix it?
A Quick reply would be awesome, Thanks.
Hi Mukund,
Thank you for your question. I work on the applications team in the high power drivers group.
It looks like the pinout in your model is wrong if you compare it to the pinout in the datasheet. I recommend using our provided schematic for simulating in PSpice. See a screenshot of the schematic below.

If this helped answer your question, could you please press the green button? If not, feel free to ask more questions.
Thanks and best regards,
John
Hello John,
I changed the pinout in my model to match the one on the data sheet but the error didn't go away.
Note that node N01540 is the highlighted node in my schematic.
Thanks,
