The high voltage converter can be used for various experiments with high electricity, as an ionizer, insulation integrity tester, etc.
What you will need:
- Linear scan transformer from any TV with a kinescope.
- Field effect transistor IRFZ44 – aliexpress.com
- Resistor 150 Ohm (1/2 W).
High voltage converter circuit
Let's assemble everything on a breadboard without soldering. I’ll just show you the work, and if you like it, you can transfer it to a more reliable board and solder all the elements.
Connecting a transistor, if anyone doesn’t know.
We need to wind the transformer winding. The high-voltage winding will be original. We take a regular, not very thin wire and wind it with 14-16 turns. We will make a tap in the middle of the winding.
Now we connect everything to our circuit. The last thing to do is connect the power. Be careful as you are working with high voltage. Do not put your hands near the switched on transformer.
Make a distance of approximately 1 cm between the high voltage output of the transformer and the terminals of the other side. And only then serve food. If it sparks, it means the generator is excited and everything works fine.
If you will use it for a long time, it is advisable to install the transistor on the radiator. And if the spark is small, then you can increase the voltage to 10 or 15 V.
