I have decided recently to try a few experiments involving high voltage, namely Avramenko's plug experiments. I need a transformer that can get me up into the 3-5kv range. Amperage is not really important at this point, im just looking for a high voltage transformer.
I have thought about winding my own, but dont want to invest in hundreds of careful turns of wire before I consult those more knowlegeable than myself.
First the perameters, the operating frequencies of the coil will be pulsed DC at 10khz or higher (definitly not into the Mhz range, closer to the 10khz side) Primary recieves the pulse, secondary needs to be in the 3-5kv range. For input I have a beast of a signal generator that will put out about 10.94 volts at 1 amp. I would like to drive it from this if possible, otherwise I will set up a mosfet driver to feed it, but I would like to use as little power as possible on the input. I chose mosfet, because I will be driving it in pulse mode, where quick on and off of the pulse are essential.
First I just tried to hook a bunch of transformers together. This worked for about two of them, then results just plain sucked. Why wont this work?
I thought of using a Flyback transformer. I opend up a large TV and found a surprisingly small flyback. There were like 15 or so leads comming out of it total, which surprised me (with my lack of modern tv electronics knowlege). Deciding to tear it appart to learn from it I found out they had enameled all of the wires which makes sense seeing that we are dealing with high voltage, and dont want Ionization or corona leaks.
Is it possible to find flybacks with only in input and an output? older tv's maybe?
Now I have a nice split barrium ferrite core with some spacers (for magnetic reluctance)
The core seems a little small to have TOOOOOOOOns of windings so im guessing that I will need very few windings for the primary, and alot of like 30 gauge for the secondary. BUT....in doing a few tests, I couldnt get readings off of any of the transformers I made with like 10 windings or so for the primary.
How many windings min do you need for a primary? does anybody have any design suggestions that can help me achieve my goal, or do I need too look down another path? Any help at all would be really apreciated.
I realize alot of people dont leave enough details, maybe I have left to many, but if you need more info on what Im trying to do, ill be more than happy to elaborate. Also, if you want an interesting read, look up avramenko's plug....one wire power transmision and longitudinal electric waves. harkens back to the good ol tesla days.
