Silent Jack Posted August 24, 2010 Report Share Posted August 24, 2010 What is the best way to generate a significant voltage, say 10,000 volts; but at a very low amperage, say 0.02? I've looked at a few different basic possibilities, but mostly they take up too much real estate. So perhaps this is more of a question of what is the most space efficient way to do this.

pyrohaz Posted August 24, 2010 Report Share Posted August 24, 2010 Possibly a flyback converter? They can usually be output current limited by limiting the current availiable to the transformer. Do you need it to be highly efficient or are you not too fussed? HaddyS 1 Quote Link to comment Share on other sites More sharing options...
audioguru Posted August 25, 2010 Report Share Posted August 25, 2010 10,000V at 0.02A is 200W which is a lot of power for a little power supply. HaddyS 1 Quote Link to comment Share on other sites More sharing options...
Silent Jack Posted August 26, 2010 Author Report Share Posted August 26, 2010 I was planning to run the project off a battery. Are flybacks an effective choice when using a battery? Quote Link to comment Share on other sites More sharing options...

Are flybacks an effective choice when using a battery?An extremely heavy car battery?Didn't you hear me that it uses 200W?A transformer is driven from an oscillator (a 200W power oscillator for yours). A TV flyback is tuned and operated at the TV's horizontal frequency (15,750Hz in North America).The output of the flyback transformer is AC.

Kevin Weddle Posted August 27, 2010 Report Share Posted August 27, 2010 A transformer will deliver a high enough voltage that you want. High voltage transformers are expensive, but can usually be found in electronics products no longer used, and be cascaded for high voltgage. Be aware that high voltage burns and shock can occur, and a high enough voltage can lay you in the hospital. HaddyS 1 Quote Link to comment Share on other sites More sharing options...
Silent Jack Posted September 13, 2010 Author Report Share Posted September 13, 2010 No, lead acid batteries are far too heavy. I was looking at maybe NiMH or more likely some LiPo batteries commonly used on RC cars and the like. Looking at 3-6AmpH class batteries. Might lean towards 12V, since there is so much standard stuff for that as far as wiring and other components. Safety is of course important and any good suggestions on grounding/shielding are welcome and appreciated. HaddyS 1 Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted June 19, 2012 Report Share Posted June 19, 2012 Generating a very high voltage with a small battery is an interesting idea. In theory, a transformer can produce any voltage, depending on it's turn ratio. They can also be cascaded. Are there any designs that utilize cascaded transformers, and if so, why isn't one transformer used? HaddyS 1 Quote Link to comment Share on other sites More sharing options...
