Introduction: ZVS Flyback Driver - Video

It has been a long time since I have posted anything, lol.

I have recently got more sealed lead acid batteries so I can now power my ZVS flyback driver up to 36 volts! I will try find some time to make an instructable about making one of those beast, at the moment, I can show the vid of it working. :-)

Hey, could you tell me how to modify the schematic to make an induction furnace?

Mvtnns (author)2011-08-11

Is it possible to use this for jacob's ladders? :P I want that stuff so bad x)

jukees (author)Mvtnns2012-11-01

yes, it is possible, made it and took 40kV zap from it, wasn't nice. :D
but the arcs climb nicely.

JoeBeau (author)2011-12-11

What is the minimum voltage required to run a ZVS driver? I was planning to run mine at 5 volts (at 22 amps) and use different MOSFETS. Would it be able to run at 5 volts or would I have to make modifications to the circuit?

I have seen this video several times but it is still awesome!

hey ive got a laptop charger is it a smps

MACKattacksnipe (author)2011-02-04

is it possible to make an ARC WELDER from this

Arc welders use High current and a lower voltage. (like 30 volts if i remember correctly)

that is a good idea, but it micht not melt the welding stuff so it might work with soldering

 Awesomesauce! Does this have any commercial use?

Plasmana (author)Kaiven2010-05-31

Awesomesauce... lol thanks!

I am pretty sure it does, probably in a newer NST, but I never seen the insides of one of those things.

Kaiven (author)Plasmana2010-05-31

 I don't know what a ZVS or NST is... xD

I guess I wanted to know more of what this is used for.

Plasmana (author)Kaiven2010-05-31

Hehe sorry, I get carried away using abbreviation and expect everybody to know it sometimes.. :)

A ZVS is Zero Voltage Switching (I know, its very technical :P)
A NST is Neon Sign Transformer

Kaiven (author)Plasmana2010-05-31

 Oh, s it is used to make halogen gases glow, right?

Xellers (author)Kaiven2010-06-01

I think you meant Noble Gasses....

Kaiven (author)Xellers2010-06-01

 Don't they use halogens also?

Xellers (author)Kaiven2010-06-02

No, you cannot use pure monatomic halogens because they are not stable elements like the noble gasses are. In fact, fluorine is so unstable that it is almost never found in its pure form; that's why they're called "Oxidation Numbers" and "Reduction-Oxidation Reactions" and not "Fluoridation Numbers" and "Reduction-Fluoridation Reactions." Chemists thought that oxygen was the most reactive element on that side of the table simply because fluorine was never found in its pure form. It's called "oxidation" because oxygen has a tendency to strip atoms of their electrons in order to form its standard state diatomic (remember BrINClHOF?), it would have been called "fluoridation" if fluorine were less reactive.

You might then ask, "why not use their more stable diatomics or other molecules that are gasses at SATP?" One reason you might want to use noble gasses is that all of their orbitals are completely filled and they are monatomic in their standard states, in other words, they have the lowest excitation energies. If you use diatomic, triatomic, etc. gasses, then you need to break more stable sigma, pi, etc. bonds than you would if you used a monatomic gas. This translates to a lower breakdown voltage for noble gas excitation and this means that you can use simpler equipment. For example, to make a good sized Argon discharge a few feet long tube, you don't even need a vacuum pump with a standard 20kV power supply. To contrast to this, you would only be able to get an inch long discharge in free air (mostly O2 and N2 gas) with the same power supply.

Did you really expect him to understand what you just said? I mean you don't even learn about sigma and pi bonds until college chemistry or AP chemistry.

Xellers (author)ubr.bzkr2011-01-22

I learned all of this in 9th grade.

Kaiven (author)Xellers2010-06-02

 Umm...I'll come back with a reply after I take chemistry... or

Teslaling (author)Plasmana2010-11-14

I tried lookin in a new NST, it was potted with white plastic stuff!

emcelhannon (author)2010-05-30

What's keeping you from using a transformer to use a wall socket?

Plasmana (author)emcelhannon2010-05-30

 I don't understand what you mean...

Xellers (author)Plasmana2010-06-01

I think he's asking why you are using batteries for your experiments.

Plasmana (author)Xellers2010-06-01

 Ahh okay, thanks, and the answer would be I don't have a big transformer, Im thinking about modifying one of my MOT's though! 

emcelhannon (author)Plasmana2010-07-12

I harvested a couple of MOTs, but can you instruct me on how to make it supply my driver?

Plasmana (author)emcelhannon2010-07-15

That would be another instructables. By doing what this guy did to his MOT's to convert it into an arc welder, but instead of using as an arc welder, connect an high power rectifier and a large capacitor (approx. 50v at 50,000uF) to your newly modded secondary. That should do as your crude high power DC supply.

Kiteman (author)2010-06-01

What a return!

Welcome back, Plasmana!

Plasmana (author)Kiteman2010-06-01

 Hehe thanks kiteman :)

I will be going in and out of instructables as I got to do college, spending time with family, doing experiments, and watching youtube. 

Summer holidays is coming up so Ill be able to spend more time here :D

(At the moment, I got too much experiments I want to get done)

randomapps (author)2010-05-31

schematic please :P

Plasmana (author)randomapps2010-06-01

Search "ZVS driver" on google! lol

I will publish an instructable of it soon too.

junits15 (author)2010-05-31

 i still dont see how anyone could feel safe around this stuff.
still really cool to watch though :)

teslafan100 (author)2010-05-30

wow. Epic, lol 5 stars

knektek (author)2010-05-30

is that capable of welding? Wish i had a flyback driver.

Plasmana (author)knektek2010-05-30

 It can make a few balls of molten metal, but it can't weld.
