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.
