Lab Requirement – How to Build a Variable DC High Voltage Power Supply

High Voltage is where all Tesla Work leads to.

Every Lab needs a high voltage DC power supply. One that be changed, lower to higher is best.

High Voltage DC is needed for many interesting experiments

  • Anti Gravity Lift Experiments
  • Radiant Energy Experiments
  • HHO Cells
  • Tesla Coils

First it is a good idea to begin by building a Low Voltage power Supply to get your feet wt if you are a raw beginner. You can turn any ATX PC Power supply into a variable DC power supply by following this guide.

Once you are done with that it is time to give High Voltage a try.


Here are three excellent high voltage 30,000 Volt power supplies that can be built cheaply.

These can be built using TV Flyback Transformers, Microwave Oven Transformers or with Car Ignition Coils.

WARNING*** This is extremely dangerous and you must take ALL PRECAUTIONS when working with High Voltage.

    And I would make sure that it is an isolation tranformer, if high voltages are involved:

    For my own part, I’m studying these things in detail beforehand so that I don’t destroy equipment, neighbours or myself.

    Nice article, I love good salvageable parts and equipment, especially when you have a good reason to customize it.

    Thank you for this, before now I never knew there was a -12v and -5v rail inside a computer PSU. This should be incredibly useful for mosfet and transistor circuits.

    dude!! im so loving your site!! at this rate working prototypes will be within reach of everyone who dares. It was a bit discouraging checking out forums coz they get hijacked by disinfo, and people who deliberately discourage laymen like myself with technical jargon…I see also a lot of issues of great interest to me like reich’s work are dealt with here.

    ps cant wait to hear from you on your electret experiment. Theres a more detailed process on Patrick Kelly’s site in the chapter on passive devices

  • MW oven diodes are rated at 12 kV. (Some are 15 kV.) The oven’s caps are rated at 2100 V, but that’s AC. With DC circuits, they can hold up to 10 kV. That’s a nice one MFD capacitor. And the magnetron tube can be used as a HV switch. Just replace one of the magnets with a coil and keep it energized until you’re ready for the switch. Once the coil is de-energized, the HV will arc from the filament to the outer case. This will also work as an amplifier. And I’ve also seen evidence of secondary electron emission when playing with that tube.

    this sounds awesome. clearly Microwave oven transformers, magnetrons and capacitors can be used for many things other than just power supplies. would love to know more.

    We have many newbies here eager to learn from such a experienced leader.
