Simulation of the Muller Dynamo

[poynt99]

Here's a sim of that circuit Ron - in generator mode.

Let me know if you'd be interested in seeing anything in particular.

Thanks!  looks good, how does the output compare with the input, not sure how to read the sim... does the output behave in a resonance manner when you vary the caps?

Ron,

I went back to a linear core with 100% coupling just to simplify things a bit.

I tried a C value of 50uF, and the 60Hz resonant L value of 140.7239mH for each of L7, L8, and L9, and the result was just a 1:1 output ratio of voltage.

Being that the L's and C's are in quasi-series and/or parallel, perhaps the values are not correct for resonance?

What do you think, and what values would you suggest?

.99, I have seen (I think) where you can make C1 and C2 variable caps in a sim, either that or sweep the frequency?

Dunno, you're the doctor

Ron,

I'm now looking at this thing and wondering "what is the big deal?". What I see is no matter which operating mode (generator or transformer), after a certain high frequency (determined by X_C), aren't the two windings just simply in parallel?

It doesn't make sense to me. What am I missing?
