Wrong! Time has nothing to do with it.Someone Electro said:You dont need all that thick wire becose its an very short pulse.
The temperature rise shows that power is wasted by heating the resistance of the wire.I found two paralel 1 mm magnet wire up to the job.It gets a bit warm afer a few fireings.
I guess the amount of current doesn't matter to you. Rub your dry hands together and you'll have plenty of voltage!danielsmusic said:does anyone have a schematic for a simple dc-dc converter up to 140v from 24v

You need a high voltage with power in it. Power equals the current times the voltage. A capacitor charge pump can't supply much current and when you use a step-up transformer then the primary current is high.A dc-dc converter would be useful but everywhere I look on the internet they are low voltage ones. Is it posible to achive 150v without ac? What about a capacitor pump or is this a dc-dc converter? i have looked eveywhere I can think of. My coil gun worked until the transformer melted, and it worked well. I don't want to use transformers.
Make an AC stepup-the-voltage circuit with enough power to do the job.
If you need 150V at 10A then it is 1.5kW!
1.5kW from a 12V battery uses 125A plus more for losses!
If your transformer doesn't melt then your wiring and battery will. :lol:
