Hello, I use a common mode choke in my power supplies, but I'm really just guessing about the results I'm getting. I'd prefer to model them in software, but I can't figure out how to include one in yours. See Fig. 8:?

Except in my circuits, the +/- rails are split with the ground in the center. I use a rail splitter circuit for that. His simulation seems to show very good performance, but I'd like to be able to do this in your software. I've tried to do it in a spice simulator like Tina Ti, but I can't get it to work. That's why I prefer your software.?

Thanks.?

Hi,

?

I'm afraid PSUD2 won't do common mode chokes due to the way the voltage sources work and PSUD3 doesn't have this on the roadmap either.

?

If I was doing this, I'd probably model it in a SPICE simulator by having two coupled inductors with some leakage, but I've no idea how much leakage to dial in.

?

Sorry, I know that isn't much help.
