Ronotte's amazing TPU experiments.

Hi Gustav,

Prendi 3 paghi 2

I do completely agree with you.

Actually I remember that one test I already did were just 'resonating' the Inner collector, I used a 3Kpf/1000V capacitor, I obtained a continous 5MHz wave with an amplitude of about 150 -200V...SOUND INTERESTING!!!!???...He He.....There were a problem: the tuning capacitor within few seconds were so hot to be not touchable......so I stopped tests as I did not find at the moment a suitable capacitor in the junk box.  I know that it seems incredible but till now re-thinking to the fact I don't find reasons for what happened....the capacitor seems still good....so I thought too much internal losses!!! ...or what other?

After that I'd to build the tpu evolution so I thought to do later additional tests (I do have still the original test ring).

So now you know the story behind.

Dear Roberto,

Yes, the 5 MHz component looks very interesting and I don't understand why the cap got hot ...perhaps a combination of DC and HV AC that bother it ?
I'm concern about the safety of my DC power supply, did you put a diode in serial with it to prevent the HV spikes to got backwards ?

All the best,

PLT

Dear PLT,

Yes there is always a diode in series to my Power Supply!!!! 
Anyway remember to choose a FAST diode (very low recovery time.....) with at least 1000V piv (like BYVxxx....).

Ciao

Hi,

I try to understand the TPU:
It is a toroid "transformer" with a non magnetic and non conductive core. There is a few windings on this which is loaded with two different high frequencies. At some points in time, two coils is inducing the exact opposite magnetic fields, causing induction in a collector coil.

I was reading the document earlier in this thread, but I lost it after a few pages - I lost it right AFTER the point where I should go directly to jail without passing Go and without collecting 200 dollars :-))

Well, I did believe the magnetic field between two opposite magnetic fields is zero, but as this is high frequency, the magnetic field is some how compressed due to the magnetic wavelength (?), right?

And where this happens, ther is energy extracted?

OK, I'll read the document once more :-)

Dear Ronotte
As I know, you have realized a practical mean to couple two fields 90 deg out of phase by cancellation.My question is:the induction on the secondary winding follow the rules of a common transformer?The polarities manifesting on the terminals of the secondary are equal or in opposition to the ones of the primary?
Thank you.
