Is it possible to simulate a transformer with 1 primary and 2 secondary windings?

Yes, even its called "turns" it means a ratio of turns e.g. primary set to 1 and secondary set to 2 is equal to 6and12, 1:2 = 6:12 = 0.5 in both cases

Not on easily EC at this time.

yes, but I mean 3 seperated windings...

@hurz How does that give you 2 secondaries? You have just connected the bottom terminals of both pri and sec, which happens anyways because both sides must be connected to ground.

@PratikP, i underatand that different. If he wants multitap transformer forget my comments. Unfortunately the author does not communicate a lot.

@Jemand123, thats impossible or needs big effort. Just placing two transforners cant work, cuz they are just electrical connected but NOT on the same magnetic core! Thats a little naive to think this is an equlivalent solution.

Yes, I would need 3 windings (with different numbers of turns) on the SAME core. Of course, I already thought that its not possible at the moment, that's why I asked the question. I hoped that maybe it's possible to add user specific blocks and type in the differential equations, or another method, I am not aware of...

@jemand123 i think you want one of those SMPS transforms, correct? That cannot be simulated easily. Like @hurz said, cascading transformers doesn't model a transformer with one primary and multiple secondaries; both transforms behave just like 2 independent transformers, either sharing voltage (series) or current (parallel) in a proportion that is proportional to the xformers' parameters.

My application is not really a SMPS transformer ;-) but a big transformer in a power plant. But as you say, it seems, that is is not possible with every circuit at the moment. I like every circuit a lot. Its very usefull!

I made you your transformer: http://everycircuit.com/circuit/6020249078726656

Wow thanks, great idea! I think this could work...

I did this some time ago: http://everycircuit.com/circuit/6662525487153152. It works just as I expected and wanted.. eventually. Notice all 3 secondaries are in parallel rather than series as above.
