In this post, I will show my DIY ZVS flyback driver high voltage generator. The ZVS driver can actually also be used to make an induction heater. But in this case, I will use it to drive a flyback transformer to make high voltage. In the video below you can see a demonstration of the arcs produced by the transformer and a Jacob’s ladder.
WARNING: This circuit has the potential to kill you. Make sure you know what you are doing and know how to handle high voltage before attempting to recreate this circuit.
I made the circuit according to this schematic that is quite popular and often found on the internet.
The components used are all listed in the schematic above. I got the flyback transformer from an old TV. And the big inductor I took out of an old computer PSU. The rest of the components you can get cheaply from eBay/Aliexpress… Or you can just buy the preassembled driver boards(see links above) if you don’t feel like spending the time and effort to make your own circuit.
Here it is in action.
