Zero and Q device

   Karlo:   Calm down, no one is killing anything.
   I ask you how you determined a 3 times increase in current, But, I get no answer.   The important thing (for us) is not that the one bulb is brighter than the other bulb. The main thing is the comparison of the input to the output readings. To really see if the circuit has merit, or not. Or, which one of the three circuits actually does something unusual.
   Sorry, I do get confused with all three different circuits, at times.  However, some nice clear input to output readings would help.

I don't have to calm down because of you. You were always ok researcher.

And I will always try to answer your question if I can.

There are 3 concepts.

We are talking about Zero circuit now.
C1, C2, C3 will triple current trough them. (law of serial capacitors, current is triple, voltage is / 3, but Czero rise voltage so voltage almost stays the same ( 175V, not 220V), so you have 3 x current, but lower voltage for a little, but not 3 times)

Czero will double voltage inside those 3 capacitors. (cap CZero will be in serial connection with grid)

That is why is more power on output.

   V8Karlo:  In case you missed it, this was Hoppy's explanation (above) of the difference in bulb brightness, and what is causing that on that particular circuit replication, in his opinion.
   I personally tend to trust his expertise in the above explanation.

Then you trust his expertise, don't try to have your own.

My explanation for the operation of the 'Zero' circuit: -

Using my 25W bulb having a cold resistance of 204R, the bulb in series with a 10uf cap and diode, the bulb does not visibly flash on connection to a 240V mains supply. However, it will flash with a 20uf or higher value cap. The difference is due to the reactance of the capacitor allowing sufficient current to heat the bulb filament to a glow in the case of the 10uf cap. The combined series capacitance of C1 to C4 in the zero circuit is around 5uf, thus no flash.

When the transistor is switched 'ON' and conducts on one phase of the mains supply, caps 1 to 3 effectively discharge in parallel to a much lower resistance output circuit, via steering diodes, to common output rails to which L2 is connected. The combined currents through the lower resistance, discharged from caps 1 to 3 are sufficient to heat the filament of L2. However, L1 cannot light on this phase as the diodes in series with the caps are reverse biased. The caps are now discharged ready for re-charge on the next phase when the transistor is switched 'OFF'.

Altering the power rating of the bulbs and cap values will alter the impedance of the input loop to an extent whereby LI may be seen to glow together with L2.

Hoopy explained part of circuit, and he did it very professional.


[Europe 220V grid]
He did not explain part when CZero making serial connection with grid and raises voltage in that line to 525V.
That explaines why you read on each cap 175V instead of 90V. That is essence of effect.

You can test it easily.

Remove CZero cap and plug in circuit in the grid.
Effect is gone and you will read on the caps only 90V or so. And the power is gone also.

So, he does explain it partially. Yes.

Nick,


We are talking about this more than 24h.
Would it been easier for you to assemble Zero in just 1 hour and see for yourself?
Just a stupid question, but...?
