@Ronotte

Your design is basically a switchmode powersupply. - there's NO chance for overunity with the design you show.
One thing that seems a bit odd is that you're also pulse-charging the cap - there's no need to do that, besides from making the circuit more complex  :o

I would suggest that you read a little about SMPS:
http://en.wikipedia.org/wiki/Switching-mode_power_supply

They're efficient, but ALWAYS under 100% (unfortunately)

... Result is that with serial connection you have spikes 5 -6 time bigger in amplitude...but not rot mag field.
In my case with Otto connection I've max 100V, with series connection about 650V.

Hi ronotte,
Can you answer a question now or later in time about - my theoretic curiosity working - if you are pursuing the rotational field or not(?), or about your results comparing both (rotational/not rot.), when you get good results of course.

@MeggerMan
Yes Rob,TL494 is a fine complete device but it isn't good for my purpose as it handles only 42V @ 0,5A (out section) and is slow also, rise time= 100 nsec. - IRFP450 handles 500V @ 14A with rdsON=0,4ohm...risetime= 36 nsec, falltime=35 nsec and is internally protected!!.
Pulse charging the cap is an easy way to do the job - a better way would be to use 'ramp charge' but for my test only purpose I think that pulse charge is nice.

@Thedane
I'm not searching for overunit with this arrangement. It's just to test & evaluate the amount of RE generation in the case I do interrupt the voltage (very quick pulse) before it reaches the iron-wire end (this is the reason to use at least 100 mt. of garden-iron wire -slow relaxation time...6 times slower than the copper and pulses narrower than 100 nsec). In this way I should be able to generate some amount of RE (Tesla did use spark gap & HV) and collect it with a copper collector coil.

@Yamanashi
Of course the test is aiming to evalute & optimize RE creation and so augmenting my actual TPU efficency. I'm thinking to pulse in this way the existing inner collector rather than the Control-Coils as I already have a rot mag field.

Anyway all suggestios are wellcome, please discuss
Roberto

Well, of course you would seperate your pulse generator power supply off from your MOSFET power supply - this would seem obvious to me.
Its upper freqency is spec'ed as 300kHz but I found I could crank it up to 600kHz with no problems, is this still too slow?
Yes, I could quote MOSFET specs all day long, but at the end of the day, its mainly what the shape of the pulse looks like on a scope and what voltage will fry it.

Are you saying that pulse or ramp charging is key to getting more energy out than in, or just a way to completely isolate the output mosfet from the power source directly?

This is a circuit I am working on at the moment:

Hi MeggerMan,
and YES I'm trying to obtain both things togheter....I agree with you that MOSFET solution isn't the best but it's easy and cheap (I pajed the IRFP450 only ? 1,25/cad)...but there are driving problems as you have to charge the input capacitance also due to Miller effect...to do so there's need of much input current....if you want to have fast rise time.....so the use of a mosfet driver like IRF7307 or similar are mandatory....you can connect directly to the gate almost every thing but then what you get from the drain is not deterministic.... :D

Your project seems nice but I'm not following the MEG.

@ rob
That is a very interesting PCB.I like it much!! Have you put a neo mag in to your rot field? if not, drop one in or use a cotton thread between two small neos suspended above your mag field and see what happens. MOAB

I'm sure you are all aware of this already, but Leon Dragone seems to have found the exact same thing with his spark-gap electroentropic device. 

See: http://jnaudin.free.fr/dragone/dragone.htm

Also, the Newman spark-gap effect could have the same underlying cause!
