@ all

Guys I need to catch up as well, Only asking the questons to help catch up

@ Otto

I think every one trusts you and are just trying to understand in detail how
you set it up, at least that is what I'm tring to do

So Otto you think I can use the curcut I posted ( not the Coils ) but use your coils

Yes, my mosfets are opto-isolated and I have them located on inside diameter of the coils. My generator is breadboard and I'm having more throuble with that so I'm considering etching the circuit.

No great changes in output until I drive above 35V. My AC component swings more negative than Roberto's scope shots.

With no power applied I see repeating and noisy spikes but at very low amplitude. I have not been able to identify an outside source but my radio hears them. They are the same level near or far from the coils (175kHz CW). I don't think they are from the coils. These are not rising and falling like you describe.

My coils are not the same as yours so I want to repeat your results first with new coils. Not much time for homework this week

@ronotte

+DCV= 18V
F1 = 35000.00Hz
F3=245000.00KHz

Look at the frequencies you wrote, do you see an error?

I think you meant to say   35 KHz  and 245 kHz   (not 245 MHz)


Also,  otto and you are mentioning this effect where the power supply seems to "float" higher in voltage.
I just realized that SM was saying the source also becomes the output and runs with gain, maybe your experiencing this phenomenon.   But then why doesn't the power supply stop supplying current?  I mean it's a regulated power supply so if it goes above the voltage it's set at it should not put out any current, or does it?

Good work guys, keep up the enthusiasm, and if it doesn't work let us "down" slowly so we don't go into a depression   LOL

...Guys, I do wonder 'what are you waiting for ?'  For the first time after a long troubled incubation, our dearest Otto kindly released his much waited interpretation of dfro's 3StackTPU:

Who is 'dfro' and what makes his/her clues any more special than any other anonymous poster?

...It is like nobody is interested!

                             IS THAT YOU DO LIKE ONLY 'ARMCHAIR DISCUSSIONS?'

It seems like you all are 'at the window' only watching what's happening and perplexed about the route to follow either as an 'armchair thinker' or just starting a brand new project with enthusiasm or again only tired & bothered.

Perhaps many of you are thinking: He He that's another Otto & ronotte Pindaric flight!.........of course I'm only jocking as this morning I do feel pretty happy...

I am glad that you were only joking.  I was starting to go into defensive mode, planning to whine about limited free waking hours and no research capitol.  And I certainly have no idea what all these beautiful women see in a poor geek like me.  Now, I am joking.

...it seems that NOBODY trusts me. Its really not a problem for me.

I know what I have. If the people dont have 2 or 3 hours to build a 3 stack TPU and test it....

The Rodin coil was the first thing that I ever tested with a "wall plug" power supply; (speaker outputs from a portable stereo.)  I always used 9V's for all of my TPU testing; perhaps this is why all of them failed.

On the other side of the coin, I have known of people and seen people test TPUs with municipal A/C power supplies.  Wow, look at that bulb light up.  Wow, feel that power supply heat up.  I hear many tales of great flashes as well.  Those failures can leave a bitter aftertaste, I suppose.

Eventually, we will need to pull our TPUs away from the wall outlets.  This is why I decided to start there with the small battery in the first place.  Hopefully, you will ween your TPU off the wall soon and it will work as intended.

If I spend any more money on TPU projects then I need to understand exactly what it is that I am doing, I can ill afford to play around like I was, educational as it was.

I have decided that the best thing for me to do right now is to keep abreast of what great folks are up to, like you Otto and all of the other 'TPU Elite' on OU, and get some Tesla patent reading in.  Speaking of 568,177, does anyone know what the voltage/current of the "direct currents" of "the ordinary municipal incandescent-lighting circuits" were, way back in 1896?

It was probably more than 9V. 

Thank you for keeping us all posted on your great works.

Great scientist may not be good electronic engineer. They may confused by circuits. What I am talking is the Voltage appear at the output that is higher than the preset value of the power supply. All electronic engineers know there is a feed back control circuit in all power supply and they are designed to increase or decrease the output when the load or power line changes as to keep the voltage constant. But they are limited to be used at a certain bandwidth. If the output has a RF component or fast switching pulses. These feed back control circuit could not follow the changes and wrongly to adjust the output to be more or less voltage. When it increase the voltage the energy drawn from the power line must be more than the preset energy. It could be wrongly think the load generates energy to the power supply but actually the energy drawn from the power line due to the lost control feedback circuit. So how to avoid this problem. I suggest off the power plug and use one or two precharged battery to get 12V or 24V to do these experiments. Or use a professional power supply that must be implemented with serious output filter and designed for RF transmitter usage. It is very difficult to find these power supplies, They are usually selled as a special made part in the RF system. I think the best and simple is to use batteries.
That will let use more concentrate to research the O.U. devices.
