But, as zcsaba77 pointed out, too high a voltage will fry your caps, it will also create arcing conditions in the coil itself and may burn your construction.

Hi Tika (and All)

I watched Naudin's video, if I good saw input was higher when NOT was load. Am I correct? Some explain why?

If spark gap too big voltage raise (runaway)? Why not put higher voltage cap(s)? or better keep voltage lower?

hi guruji

if u left too far spark gaps catodes, cap(s) explode? this coil is air or ferrite cored? how u calc how much turns need forward and back?


Hi Zcsaba77 to tell you the truth I'm still wondering how I did the setup of the flickering lights cause I changed alot of setups.
But yes as I think you already know if a cap is charged beyond it's voltage it can explode especially when using a ZVS.
In one of the posts King said to crush ferrites and do a form you need; did you do this? Do you use special type of glue?
Grumage can you please post your flyback schematic?
Thanks

Hi guruji,

I'm sorry I don't have a schematic. I was using a standard B/W TV unit as is. This runs at a frequency of just over 16 Khz (raster scan for 625 lines) But as quoted yesterday, I felt the HT spark did not have enough energy to do the job. A colour TV flyback has a much higher output in the order of 25 Kv but still runs at 16 Khz. My own feeling is that the Flyback oscillator frequency should match the resonant frequency of our Primary L C circuit. This would then minimise the primary's energy requirement.

Quote, Zcsaba77. I don't think we need ridiculously high voltages, I proved that yesterday. Both input sources to my primary winding were aproximately 8Kv. But the bigger windings of the 50 Hz ignition transformer were providing a better spark. Only problem was the frequency.

Cheers Grum.

Naudin's experiment was part of a series of experiments on the newly discovered "Delayed Lenz Effect".  The lowering of input current under load _is_ that effect.

There is also the insulation between coil loops to take into account, and spacing between cap electrodes.  3 inch is 76 mm, to bridge that you need about 85kV.  You will need to build your own parts rated at 100kV or more, potted in epoxy or (and?) swimming in oil.  You will also need higher current, and power to drive such a supply.  I'm not saying not to do it.  It just doesn't seem practical unless you want to produce over 100kW, which implies bigger, and more expensive, everything.

What voltage do you use to power the flyback?  These B/W transformers were usually designed for a 150VDC supply.  Did you coil you own primary and feedback coils as is often done ? 

For the frequency, I think you are right, the primary resonant frequency should match, or be a multiple of the flyback frequency for optimal operation.

As for me, I do not have 5W resistors, but tons of caps, so I will make a driver based on the SR193 schematics.

Hi Tika,
I was using the the whole Portable TV as, is obviously without the CRT!! Just a small 12VDC plugin power pack of about 1 Amp. But it does not have the punch!!

for my initial test using a flyswatter circuit with a power source of 5 v dc rechargeable batteries  I can produced plasma on both flybacks and probably more can be handled using one primary source.....  to convert that plasma to a resonant coil then to a load will be my objective for now
tomorrow I will try to use a 220 v to   12 v ac transformer step down  then to the coils of the 4 flybacks via a 130 uf 450 v ac cap and a dimmer switch....  will use liquid nails for sealant   as shown on the yt

Hi Guruji

What is it ZVS? These abbreviations not say me too much (ZVS, IMO, etc). Have not own aparatus, but I want in this year start with, now I just ask, and want to learn from experiented people :)

HI zcsaba77,

I too am in the dark with ZVS?  However IMO means, In My Opinion. I hope we can all learn, like you, from this more practical and nut's and bolt's hand's on thread :)

ZVS is short for Zero Voltage Switching  i.e. you operate the active switching device when the AC waveform to be switched just goes to zero voltage. This way the device dissipation could be kept at the minimum possible. Here is a link:

I found this video on ZVS: http://www.youtube.com/watch?v=0ONq3DxXE2w

Hi Grumage

If I good understood you have NOT frequency adjustable HV transformer, and you wanna(must) build coil exactly what can resonate good, or you tried build adjustable coil (sliding contact on coil)?
You supplied by 8KVs? but if you did some turns on primary coil, it should be amplifying effect, because one turn voltage over 100Vs (maybe much more).
Your apparatus is air or ferrite cored?

Hi zcsaba77,

You are correct. I do not have a variable frequency HV supply. Neither do I have a variable primary. The core is loaded with 10 by 38mm Outter Diameter 13mm Thickness Ferrite Ring Core Tube Toroids
@ 12.0uh. 5 at each end. Gap in the middle.Primary coil is 200 turns 22 SWG (steel wire gague) with an inductance of 2mH.
HV storage capacitor 6nF @ 16KV. So if I am correct I need an HV frequency of 45.94 Khz to be in resonance.

I am going to try this drive circuit into a Motorcycle ignition coil and see what happens. Will hopefully be able to let you all know later if it has worked.

Hi Grumage

Can you build coil exacly to 16KHz? you not tried less turns (example just 1/3 of 200 = 66)?

Hi Gyuszi

This video looks like circuit diagram about induction heater ::), if am I correct.
This type circuit is ZVS?

Hi Grumage and Zcsaba ; yes as gyulasun said ZVS schematic is on the net if you google. This driver is very wild and deadly too cause it can pump alot of ma in a 1inch or more arc so if you're planning to build this be aware of it.
Today I remembered the setup I did last time as shown but changed cap to a 2500v smaller cap.
Another thing how can one do multi quote on this forum?
Still nothing OU yet cause I lit a 25w bulb I think same as input now.
