My first results in building a Tesla Coil were encouraging, but running the whole system on a battery pack with a 555 driven flyback transformer was not the best I could get. Still those of you interested in seeing my first steps in the Tesla Coils realm can have a look here
My second attempt and the subject of this article, came with a change in the power source.
As advised by Teslina I tried to use a ZVS driven flyback with builtin rectifier to power the tesla coil.
For the flyback, first I’ve tried a twin setup, by using two monitor flybacks, both with built-in rectifiers.
The primary must be shared, and the two secondaries connected in series for summed voltage output:
Luckily I’ve found a better flyback that did the job of the two, so I dropped the design above. Still it’s useful when you want to get a bit more voltage and you only have small monitor flybacks.
I’ve used the half wave rectified output to charge a bank of capacitors, summing 6nF 18KV. Here’s the simple Tesla Coil schematics for rectified current:
And here are a few pics and vids showing the Tesla Coil in action:
