If you have need for 30,000 volts to launch your ionocraft (lifter) or power other DIY projects then shuttle over to RimstarOrg’s YouTube channel and checkout [Steven Dufresne’s] homebuilt 30kV power supply. The construction details that [Steven] includes in his videos are always amazing, especially for visual learners. If you prefer text over video he was kind enough to share a schematic and full write up at rimstar.org.
The power supply can be configured for 1.2kV – 4.6kV or 4kV – 30kV at the output while requiring 0-24V DC at the input. In the video [Steven] tries two power supplies. His homemade DC bench power supply at 8V and 2.5A and also a laptop power supply rated at 20V 1.8A DC. A couple of common 2N3055 power transistors, proper wattage resistors, a flyback transformer and a high voltage tripler is about all you’ll need to scrounge up. The flyback transformer can be found in old CRT type televisions, and he does go into details on rewinding the primary for this build. The high voltage tripler [Steven] references might be a bit harder to source. He lists a few alternates for the tripler but even those are scarce: NTE 521, Siemens 76-1 N094, 1895-641-045. There are lots of voltage multiplier details in the wild, but keep in mind this tripler needs to operate up to 30kV.
Join us after the break to watch the video and for a little advice from Mr. Safety.
What good is a high voltage power supply if you don’t travel around in a homebuilt ionocraft just yet? Well maybe you need to electrify your Wolverine claws or Thor’s hammer. We couldn’t close this article without a shout out to the master of high voltage hacks [Photonicinduction] now known as [Photonvids] on YouTube.
Time for Mr. Safety:
Q – Mr. Safety, Is this dangerous?
A – Very! Do not try building something like this unless you really know what you are doing. You can easily be killed by the output and by other points in this circuit. Follow [Steven’s] safety tips when operating such a power supply. Remember to ground the outputs after shutting down. The high voltage tripler can store quite a jolt in its internal capacitors so be careful with that device in and of itself.
