Here is a list of high voltage power supplies with schematics and construction details, going from simple to complex. Be careful if building any of these, high voltage can be dangerous! Simple flyback driver 10-15kV Probably the very first high voltage device built by any enthusiast.

It uses a power transistor (2n3055) and two coils: a primary and a feedback on a flyback ferrite core. Schematics and details: 2. Push Pull (dual) 2n3055 flyback driver You can use 2 x 2n3055 transistors in a better circuit that provides more power. However this too is prone to failure due to the transistor limitations.

Project description This simple circuit is one among commonly used ignition coil drivers. Ignition coils are a kind of high voltage flyback transformers used in automobile ignition systems. Much like HV flyback transformers in cathode ray tube screens, they are driven by voltage pulses provided from a DC power supply which is interrupted by a.

A large heatsink is required as well. Voltage multipliers If the flyback doesn’t provide the voltage you require, a solution is to build a voltage multiplier. You can hook it to any flyback secondaries that doesn’t have built-in rectification (diodes or multipliers).

A very easy to build design is the Villard cascade voltage multiplier: To understand how it works, you can read more on it. I’ve built mine in a plastic CD box, this way I can add liquid wax for better insulation. Here are some interesting tests using the multiplier: 4. 555 Timer flyback driver This circuit uses a 555 timer IC to pulse a power transistor with square wave at a frequency that is set by the capacitor and the potentiometers.

It is a very efficient circuit, assuming the frequency is correctly adjusted. Circuit diagram: See it in action. 555 Timer dual ignition coil 30KV An even better approach for those that seek more power and higher voltages is using ignition coils from cars. I’ve got 2 from a scrapyard, and connected them in anti parallel: The driver used is the same as above (with a 555 timer), the difference is in using a different pot, resistors and capacitor for another frequency interval, and stronger mosfet, suitable for ignition coils: Adjusting the frequency with the pot, I got some tick white arcs, similar to those produced by a flyback with a ZVS driver.

A good indication of the power running in the system. ZVS Flyback driver A powerful driver with excellent results (no transistor heating, a lot of power pushed), is the ZVS (push/pull) driver, that was described in.
