I use LTSpice and qucs, and no I haven't tried simulating this circuit. But I think the "Itsu redraw" schematic looks like it comes from a circuit simulator.

Yes, it was drawn up using MultiSIM BLUE (which you can get via Mouser.com here ) but not for simulating as that is an art on its own which skills i do not have.

What is the definition (Nelson's preferably) of "HV Radiant" and how is it supposed to manifest itself in this circuit, other than blowing up capacitors and transistors? The HV part I understand, I think (for me it means generally over 1kV) but what about "radiant" ? Is that OU-speak for broadband RF noise, or does it mean something else? 

As far is i understand, yes, its OU-speak for broadband RF noise. but hopefully Nelson is willing to explain this.

I must say, when I opened this thread this morning I was rather put off by what I saw. It's enough to trigger the transformation of a nice placid TinselKoala into the dreaded Drop Bear.

Hopefully the nice placid TinselKoala in you prevailed

Hello,
    I mounted on the bread board a copy of the circuit with different components and the result is almost the same, about 360 volts no-load (220 volts with the LED lamp load) output HV and tens of volts on the "charger" LV output; wave frequencies between 10 and 15 KHz.
Does not always work on the first shot, it is necessary to find a particular point between voltage, amperes, components used to obtain the oscillation and the output voltage peak. For me 5.5 volt 0.3-0.5 A.
As others have pointed out, sometimes the oscillation is fleeting and I burned a lot of transistors in the test.
Even by varying the transformer (9, 12 or 24 volt primary, secondary 240 volts) or the diodes bridge or transistor or the toroid (2 to 6 inches) does not change much.
I believe that this circuit is only a starting point in the work of Nelson and that he has used this as a starter to generate HV that in another way it is managed.
The point now is this: what we do with this HV?
In itself the circuit does not self-running:  I tried to loop using the energy in HV output with a step-down transformer and that of the LV output with capacitors without result. Other ideas ?
What do the Kapanadze boys with high voltages? How to play with this type of energy?
As we move forward at this point?

Hello Icarus
Thanks for your report, very interesting, I had no idea so many people were working on this. I hope you don't mind some questions.

How did you connect your transformer primary and secondary? I am still unsure about that.

Did your diode bridge on the HV end still work normally when removed from this circuit and tested within its normal operation range?

Do you think the main purpose of this circuit is to generate HV, or is the charger side the main purpose?

I read that you tried self-looping from both outputs. Did you try battery charging instead of cap charging, and then running the circuit from the battery while charging another one?

Do you have any scopeshots you could share?

Thanks in advance--

Good morning all.

I've just read that Chet has suffered a re occurrence of his recent problem, I would openly like to wish him well and a speedy recovery. Get well soon Chet.

What's the consensus? A quick zip around with the vacuum? Tidy the thread, so to speak?

That's all for now folks.

Cheers Graham.

Some answers to TK
How did you connect your transformer primary and secondary? I am still unsure about that.

If you want to HV, the primary on collector of the transistor and on the positive;  on the secondary you have HV

Did your diode bridge on the HV end still work normally when removed from this circuit and tested within its normal operation range?

I used a diodes bridge made of 1N4007 and another of SF28 (fast diodes 2a 600 volts); diodes continue to operate normally

Quote from: TinselKoala
Do you think the main purpose of this circuit is to generate HV, or is the charger side the main purpose?

I think this circuit is a HV generator (or radiant energy generator, whatever that means) and that the charger side is a side effect

Quote from: TinselKoala
I read that you tried self-looping from both outputs. Did you try battery charging instead of cap charging, and then running the circuit from the battery while charging another one?

I tried to charge a battery on the LV output and another battery on the output of the step down transformer, in turn connected to the HV output: the batteries charging but more slowly than if they have a power supply (another battery)  that feeds everything

I'm working on it. Something you can find in my previous videos

On the bench now.

Thanks Icarus.

Just one more:

Let's be very specific here: By "primary" do you mean the 24v side, and "secondary" the 240 volt side of the transformer?



I'm used to thinking about transformer windings as Primary = the driven or input side of the transformer, and Secondary = the output side of the transformer, so using my "definition" whichever side of the transformer is connected to the collector and positive rail is the "primary".

Yes
Primary 24 v
Secondary 240 v

Hmmm,  in my part of the world, the 240V would normally be the primary.

Sure, because normally (in any part of the world) with a step-down transformer you'd connect the 240 volt winding to the power source, and take the 24 volt winding to supply your load.

But it is certainly possible to connect the 24 volt winding to an AC power source of the right voltage and impedance, and then connect the 240 volt side to a compatible load. In this case (step-up) wouldn't you consider the 24 volt side the "primary"? What if the same transformer were labelled as a "step up" transformer rather than a "step down" transformer, would that make a difference in which side is called "primary" ?

This is why it is important to be very specific in questions and answers, particularly since we are dealing with many languages and many parts of this world.

I would like to get some clarity from Nelson himself on this issue. Which way does Nelson say the transformer should be connected, and please answer by using the words "24 volt winding" and "240 volt winding" instead of "primary" and "secondary". This way there can be no ambiguity... I hope.

Dear All.

So are you saying we do not actually have the complete schematic? Or that this device in the photo is not even the same one we have the schematic for?

If it is "just" a mini exciter radiant thing, I have a much simpler schematic that actually works, is repeatable,  and doesn't cause components to fail. It also looks much cooler.

OK, I need some clarity here.
 
1. Just what are the claims made for Nelson's circuit that we are examining here, other than that it causes components to fail and makes funny scopetraces?
2. Do we have the correct and complete schematic?
3. Which way around does _Nelson_ say the transformer needs to go, using the "24 volt" and "240 volt" winding terms, not "primary and secondary"?


Sorry if I seem a bit snippy this morning. I've been feeding trolls and while that is all good fun, it does get rather tiresome at times.

Actually you just got finally relevant here. I did ask the same questions before two days already here - and I was deleted from here  with @grumage for being "offensive", "impatient" and "off topic" ("just wait, we are friends on background you know"). Whereas in fact I just denominated the problem of many threads in this forum clearly.
