High Voltage DC
Do a google search for flyback+tesla coil and you'll get loads of hits for a
very popular, very simple one or two transistor high voltage generator. Here's one link... http://www.aaroncake.net/circuits/hvgen.htm With 12V input, you can get around 8KV output. Add a diode to the outpu and you get 8KV DC. Reduce input voltage accordingly to get 4KV. There is also a cct diagram for a 4000volt DC supply in one of Robert Ianinni's books (He of Information Unlimited fame.) Cheers. Mark H. "Ed" wrote in message ... Hello, I would like to make a simple DC power supply capable of giving around 4KV. The current only needs to be small. Is it possible to make such a power supply that runs off a 9V battery? If it is, can anyone give me some pointers on making one, links to schematics would be even better. I'm hoping I could use an off the shelf transformer, rather than making my own. Thanks in advance, |

High Voltage DC
You can also use the inverters from an old disposable photoflash unit
in combination with a cockcroft-walton multiplier. I have some schematics at http://home.satx.rr.com/worpjr/Physi..._cockcroft.htm If you need help gutting and modifying the inverter, just send me and e-mail. The unit i designed and built was for around 9 kV, but you can scale it down if you want.. The voltage from a CW-multiplier is close to (Source voltage) * 2 * (Number of stages). The voltage on each capacitor should be rated at least 2 * Source Voltage: peak to peak, not RMS. Best Regards, - Joshua. "Ed" wrote in message ...
