minor threadjackthis was keeping me awake last night.
Are there any electronics boffins here who can tell me what this would do?

Almost nothingis my opinion. But I am sure somebody else will be able to improve on that

well sometimes you'd be surprised what stuff does.I made a physical analogue of this ages ago when I was trying to invent a constant engagement continuously variable transmission. Which is supposed to be impossible, but I'm telling you it's not.

are those supposed to be coils?because I don't know either way.

not a loterr, looks like a complicated way of doing a 1:1 transformer, But need to know the turns ratios the be precise.

assume # of turns is proportional to # of squiggles.my thinking is that, through one circuit, it's step down, but through the other, it's step up, so it could be 1:1. Or it might not be. Depending on which way the current wants to go.

Putting AC thru it would be odd.Phase would change on output.

it would have to be AC, or it wouldn't do very much at all.you could also introduce LC filters in the middle, for lols, to get a transformer whose ratio depends on the frequency.

non issueit's balanced just switch over the connections

yepon the LHS the upper half of the centre section looks like a 3:1 step down, in phase with the lower half which looks like a 3:2 step down. And on the RHS vice versa, overall giving you in=out

but that's assuming equal current distribution between the two paths,which isn't necessarily the case for all types of output load. I've a feeling the overall ratio could be quite unpredictable.

possibly but not necessarily.If we're getting into that level of detail we need detailed specs of the two transformers.

I'm going to have to make one, I think.It's not going to blow my house up, despite the concern expressed above. At least, not if I only use low voltage.

I'm intrigued nowWhat do you expect?
it's going to give you in=out unless you go to too high or too low freqs or too high or too low power loads, and then, unless there's some odd unbalance in the transformers or wiring it'll be nothing unusual

Would it have some capacitance?(Reading between the lines {;-) )

everything has some capacitance.which raises an interesting point about the gate charge of MOSFETs in switching power supplies.

and PAL and NTSCNTSC (Never The Same Color) bolloxed the colour on US TVs due the base emittter capacitance variation of transistors changing with DC offset, PAL (Pricey And Late) overcame this with an expensive modification

I know nothing about electronics.I don't even know about stuff like the differences between voltage and current.
Now, if you were to express a circuit as a weighted graph, on the other hand....
(actually come to think of it, I only really know about unweighted graphs, so never mind)
