Coupled Inductors

Other Parts Discussed in Thread: TINA-TI

Is it possible to have more than 2 inductors coupled with Ti-Tina? LTspice allows arbitrary number of coupled inductors with the K directive, I am hoping for something similar.

Thanks,

I am investigating this currently. Currently, the only way I see to use coupled inductors is the standard 2 coil setup.

There may be a way to import a .SUBCKT with the coil setup you want to use with the New Macro Wizard. It would use the .SUBCKT as your custom coil set up and use the same coupling coefficient for multiple coils in the .SUBCKT. I have not done this perviously, but conceptually, it may work. I am checking on the support for these statements in TINA-TI now.

I am attaching two example files that show you how to do this. One is based on a schematic and the other is based on a subcircuit import.

Please see the attached .TSC files.

Thank you, the subcircuit import looks perfect. It looks like it should be straight forward to extend to arbitrary number inductors (with appropriate symbol edit and subcircuit edit). Thanks again,
