This device allows up to 40,000 volts by 220V AC. The AC to AC Converter circuit is powered from the mains through primary transformer (220-24) to isolate the network while reducing the input voltage.
Here can be used as a fly-back transformer from a TV which is not used. Better to use a primitive type, without tripler or high voltage diode. This type of transformer is initially allowed to obtain ten thousand-volt voltage easily.
Power winding (formed between points C and D) is comprised of ten turns of wire AWG18 with a center tap (ie, five turns, the center tap and five turns over).
The control winding (formed between points A and B) is composed of four turns of AWG22 wire with a center tap (which would be equal to two coils, the center tap and two turns over).
The transistors must be properly dissipated to avoid heat problems of temperature.
We can make this device portable by simply replacing the source of AC-DC with 24V battery.
Operating voltage of these devices is high. Harmful to humans, so take extra precautions when handling.
