The Best and Easiest Way to Drive your Flyback

Picture of The Best and Easiest Way to Drive your Flyback

In this instructable I'll be showing you a super simply way to drive your flybacks! because i know for a fact that I'm tired of transistor type drivers and even the ZVS's are a pain. So get ready for this because I'm sure it'll make you excited as it did for me! heres my video tutorial for some more help.

Step 1: Materials and Important Tools Needed

Picture of Materials and Important Tools Needed
  1. A Florescent light ballast: got mine off of amazon. just look for anything called a ballast. very old types done work, they use low frequency. so find a newerish kind.
  2. You'll need a flyback of course, get a nice big juicy one for some good arcs! and remember, older the better!
  3. A multi-meter is used to find your HV negative and primary coil in your flyback.
  4. something to submerge your flyback in. you'll want a sealed container, fill it with mineral oil and use that to insulate your flyback. if you dont do this, your flyback is likely to arc to other pins and will burn out.
  5. other commons like soldering iron and wire stirppers. you'll also need a 120V wall plug cord for the ballast.

Step 2: Setting Up the Ballast

The Ballast has a few wires that need to be sorted out. On one side you have white and black input wires for 120V AC that can go strait to your mains. so simply attach a power cord to that. On the other side there are two sets of wires that are clearly seperated. dont worry about one set, tie it off because its unused and will only get in the way. now the set you are using(red or blue, which ever you choose, ill be using blue for example) will have two of the same color and 1 yellow.(im basing everything off my philips advanced....) connect both of the blue wires together into one lead, now that one blue lead and the one yellow wire are the wires that are connected to your flybacks primary coil.

Hello, I just got a Philips Basic 32w for 1 lamp ballast and tried to power a flyback, and when it starts up, I can get just some little sparks and after 3 seconds the ballast shuts down. Any ideas?

Why not just hook the ballast to the Tesla Coil? Wouldn't that work? I was thinking about doing that with mine. I don't know, but it seems like it should work (I hope because I hate zvs drivers and all that).

ill try it out! hopefully i dont burn it up hahaha

A Tesla coil and flyback are different from each other because a flyback has a ferrite core( iron) a Tesla coil does not. A Tesla coil has nothing to focus the magnetism produced

i tried it out and got nothing, i dont understand how exactly flybacks are setup differently to understand, because your right, a flyback is kinda like a compact tesla coil in many ways, ive actually used them to make a mini SGTC

I made one of these circuits, and it works great!!!!!!

The person I asked told me I should put the cap and resistors on. I don't really know. All I know is that I hooked my smallish one to my pretty large coil and got at most about 1/16th inch arc from it. Ballasts are better for flybacks, except my ballast doesn't make very large arcs with the flyback. I should put it in oil.

are you sure your using the correct pins on your flyback? use your ohm meter and find the two pins with the most resistance between each other. when i first started i made the mistake of using pins that had continuity, that was incorrect. once i found the right pins i got insane output. but ya, oil bath on the flybacks is a 100% have to. find the pins, solder some wires to them, and dont power it untill its in oil because it will never work as well untill its in a bath

Yeah. I went on electrotech online and asked someone. He said to put a low farad rating capacitor from the ballast and some high resistance resistors in series. I'll try it soon if I can get a ballast.

so your saying to add a cap and some series resistors in parallel with the ballast and coil or in series?
