Any simulation software for circuits that can do multiple air core transformers?

    I need a circuit simulator which can get me the voltage and current at any point in a 4-coil transformer setup. So basically I have 4 coils which are linked to each other and they are all non-ideal air-core transformers. I need to get the voltage induced in each coil and the current running through them.

    No one knows??

    Anyone can help me on this?

    Why won't LTSpice work for you?

    I don't know how to model it ...that's my issue. How can I model 2 set of transformers all together?

    So i have: Coil #1 & Coil #2 --> Inductively coupled
    Coil #2 & Coil #3 --> Resonant coupled
    Coil #3 & Coil #4 --> Inductively coupled

    I want to model this in some simulation software so that when I give it an input to coil #1 I want to know what I receive on coil #4 (and so on for coil #2 & coil #3 but mainly the load coil which is coil #4).

    With LTspice (and probably any other spice), you would have to know mutual coupling coefficients.

    Ron beat me to it but in LTSpice a transformer is modeled as a pair of inductors with a defined coupling coefficient. Join the LTSpice Yahoo group and ask the wizards there how to do it. You'll be inundated with answers.

    Edit: This simulator is terrible...its so hard to use...is there a more intuitive one where you can just drag and drop components instead of having to type in stuff for every component?

    What simulator?

    If you think LTSpice isn't intuituve, you'll really be disappointed in other simulations.

    I like Multisim, it's very nice but I don't see any air-core transformers in the component library where I can specify the coupling coefficients and mutual inductances....darn it!

    you saved me once again Brownout, thanks ! I had Multisim v11 installed and it doesn't have these components in the library.
