wanted: how to build a dc rectifier for neon sign transformers Answered

please help me build a dc rectifier for a 10 kv neon sign transformer. i need it to be dc becouse im building an anti-gravity lifter and those dont work with ac


Would a rectifier from a PC power supply work. Let me know if these will work because I have some.

exist diode like you need !
i built a lifter last year :http://www.youtube.com/watch?v=4t_Ut1gG7wI
you can find useful information on lifter high voltage rover supplies on http://jnaudin.free.fr/lifters/hvps.htm
10KV may not be sufficient, I used a HV power supply from an old CRT monitor.
Lifter work olso with pulse DC current

Que? You want to rectify 10KV? Maybe if you told us about the crack-pot "anti-gravity" thing we could dismiss it properly? (I am a natural cynic) L

It is not true anti-gravity but rather a flying vehical that lifts itsself by directing ions downward which also forces air down. Google it or the biefield-brown effect and you'll see what I mean

Sorry about the previous comment - I was in an odd mood. Well people can obviously get these things from somewhere, but you obviously want to use what you've got. I'm not too sure. Are you just aiming to make a 'lifter' or is this something more? L

just a lifter for demonstration purposes

Yeah, I found a few, but short of "my dad provided a supply from his company" I didn't manage to find much information on the supply. However, I got the impression that maybe a pulsed DC system might do it for you.


i could possibly use a pulsed dc system and then put a high voltage capacitor in series with the hv lead to even it out

I don't know that pulsed would be a problem if the frequency is high enough? L

well how dou you suppose i get a pulsed dc?

no, you need to put the rectifier after the transformer becouse other wise it wont work. or it would have to be pulsed dc and even then the output would be ac

dont you know that transformers can work on AC and DC. it really doesnt matter if its before or after you rectify it into DC. the only thing is cost, to find a rectifier that can handle 10KV of power. finding a rectifier to convert 120 volts at 15 or more AMPS is easy and doesnt cost any more than $10. it can also be used on many other things too.

it will only work on pulsed dc. not normal battery-type dc

mine do! but if you need a "rectifier" look on ebay!
