see Cravens Wanlass:

patents:

http://www.google.com/search?tbm=pts&tbo=1&hl=en&q=%2B%22Cravens+L.+Wanlass%22&btnG=Search+Patents

Right on!  The first patent posted is probably the easiest to implement, but the Wanlas 1980's patent shows you can take this as far as you want...

"SUMMARY OF THE INVENTION
The present invention overcomes or reduces the foregoing disadvantages of electric machines by providing a capacitor in series with a stator winding thereby defining a series circuit. Connected with the main winding is switching means which operates in response to signals from an external trigger source, together with the capacitor and main winding to permit sequentially current flow in opposite directions. The switching means, capacitor and windings are fed by a source of D.C. voltage and this is converted by the series circuit, and switching means into a clipped A.C. square wave across the main winding. Frequency variation of the A.C. square wave is obtained by varying the frequency of the signal from the external trigger source, the signal preferably being discreet pulses.
The electric machines of the invention provides a system in which the magnetic flux density in the stator is maintained at optimum level for requisite load conditions. In addition, the system permits the current in the rotor also to be maintained at an optimum magnitude for requisite load conditions relative to those permitted in convention electric motors of the induction type, and the torque and horsepower of a motor for a given amount of magnetic material to be optimized."

Good find!  So the question is does it work as a generator?

I'll sim it up and we'll see. Someone might build one and try as well.

@poynt,

From what pspice library did you select the transformer you used?
The only one I can find is 'breakout.lib', but that one does not have 2 secondaries that do not have a common connection.

Did a test on the world patent today and it is a good producer... but reflects back to Prime mover

27 1/2 watts out but at a cost of 32 1/2 watts extra on PM

Middle coil...20 + 20mfd

I always use separate inductors. Then you choose a "K" (core) part to couple them. You can couple up to about 6 separate inductors to the same core. In the "ANALOG" library, there is a K-Linear part. I use that and also the non-linear Ferroxcube cores supplied in the full version.

HTH,

Good stuff Ron.

Will be interesting to see how it sims out.

   If you are looking for some numbers on what it would do as a
generator then d/l the pdf I have. google esl-ie-84-04-137.pdf and
it should be the first entry. Address is at tamu.repository.

Thanks Thay,

Have you done any work with this?  I can tell you that a concentric wound bifilar doesn't work. In the tables at the end of the PDF there is a column for "control degrees" is this the offset between the windings do you think?

In the one tiny sketch it shows the 'control winding' in a different slot but here again there is a lack of clarity and detail necessary to replicate.

   None at all. Just read someone ask if it had been used as a gen. Just happen to be reading the file at the time and passed it on.

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 XC), aren't the two windings just simply in parallel?

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