How to Make 30kV High Voltage DC Power Supply with Flyback & Cockcroft-Walton Multiplier Tripler
- 7年前
How to make a high voltage DC generator/power supply using a flyback transformer and a Cockcroft-Walton voltage multiplier or 30kV tripler. This one generates up to 30 kilovolts with milliamps of current. I demonstrate it using sparking and by powering a lifter or ionocraft.\r
\r
It uses:\r
- 220 ohm, 3 watt resistor\r
- 27 ohm, 2 watt resistor\r
- 4700 microfarad, 35 volt electrolytic capacitor\r
- two 2N3055 power transistors\r
- flyback transformer with no additional electronics attached to it\r
- 30kV Cockcroft-Walton voltage multiplier, also known as a 30kV tripler\r
\r
I show how to power it using my homemade 24 volt power supply, a simple wall adapter and a laptop power supply.\r
\r
For a video showing how I fixed this power supply when it broke, watch this:\r

If you want to make your own tripler/Cockcroft Walton voltage multiplier, see my webpage here as a starting point:\r

For a flyback transformer without a built-in diode (the one for this power supply must not have a built-in diode) see here:\r
\r
The Sanyo F 0241 listed there might be a good one, but I cant say for sure.\r
\r
WARNING: This power supply delivers a lethal amount of current, in the milliamps. It is not like a small homemade Van de Graaff generator whose current is in the microamps. Notice the precaution of using a grounded discharge stick in this video. Do not make this one unless you understand how to use it safely.\r
