help.. Capacitor charger

[drin_pogi]

mga boss meron ba kayo circuit dan ng capacitor bank charger? 400 volts po rating.... gagamitin ko po sa coil gun... yung automatic na kagaya ng camera flash

[rdpzycho]

'yung sa studio flash, rectifier, tapos SCR ang gamit, then comparator sa capacitor bank para malamang kung mag-charge na ulit.

[drin_pogi]

panu kaya ang circuit nun?panu kaya gamitin ang comparator?

[insomartin]

Coil gun? mahirap yan dude. materials pa lang hard to find na. ingat ka ah. kung gusto mo mag venture sa tesla coils and Flyback, at marx generator. you know who to call.

[drin_pogi]

meron na po ako flyback driver eh.. lakas ng arc 2 inches... meron na rin ako tesla coil.. kaya lang hina ng output.. flyback driver lang kasi gamit ko... plagay ko mahina yung current supply ko...

[insomartin]

Neon sign Transformer gamitin mo. cheaper kapag 2nd hand. ginagamit ko ing yung nst sa nga high voltage testing ko. nakakatakot lang mag neon sign kasi ang lakas nang arc. di tulad nang flyback manipis lang yung arc. kapag sa neon sign pwede kna makatunaw nang GLASS. actually ayun ang mahirap. kahi kahit sparkplug nang kotse natutunaw. tungsten dapat electrodes mo sa sparkgap. and pulse grade caps gamit mo.

HI to all here

First of all I'm new here and sana welcome ako, sino ung nagtatanong about sa Capacitor charger??? about developing a coilgun.... eh just message me in my other email >>>>>> girudo_sinister@yahoo.com and maybe we can collaborate and discuss things....... and also here in this forum...... I'm also a Die hard enthusiast and hobbyist for coilgun projects and other stuffs....... and I just got a few and little knowledge in electronics which I aqcuire on my own....... so I welcome ang mga magrereply......

@Zeero Cool Crash OverRide welcome po sa forum... enjoy... probably you learn more about electronics here in elab... and of course help others by sharing your expertise as well...

OT: Nice username... love that movie

@drin_pogi,...you can use EMCO F15 model for charging capacitor bank up to 400V,..and must have a voltage reference to be used in your comparator,,MOSFET(as a switch) and resistors,..from Vcap use resistor in voltage divider going to your comparator to lowar the voltage the comp input,,another input of your comp should be a Vref,..so that if the Vcap=400V that comparator will change the output voltage and drives the MOSFET to stop charging,,..

@akhen - thanks dude so you also knew that movie, that was one of my favorite...

I have tried so many Booster Circuit for HV application few of them works but, I tell you when I am already installing it to my own designs and applications suddenly it wont work, I got a doubt to my self that messing around with oscillator ICs, Comparators, MOSFETS are really a nuisance since these devices are sensitive to human static discharge maybe I always damages them that's why they fail to worked at all, recently I got a blown path in the Circuit that I have made, probably a shortage happens in its path....... now I'm messing again with the circuit.......... the Voltage regulator works fine it has an input of 12 to 24V the output for the oscillator IC was 12V and for the inductor would be 12 to 24v..... the oscillator IC works fine, it just so happen that I got a problem with my indicator using the comparator IC LM393 or LM311 or even the transistor 2N309 with a potentiometer hook up on it, my problem was it the whole circuit doesnt stop charging and the LED in my previous configs. lits but the cycle doesnt stop even if the Reset Pin in the oscillator IC was hook up to the comparator or the transistor...... I'm using the LM555 as an oscillator, by the way correct me about this if I'm wrong the Reset pin in the LM555 timer was used to stop the cycle when the cap voltage was reached and then turn on again and sends signal to start and maintain the cap voltage if the cap voltage decays by nature???

I got another question which was a nuisance in my mind, pano ba ang tamang placement ng resistor sa isang circuit indi ung soldering ang ibig ko sabihin kundi ung pagka ilalagay mo na sya sa isang solderless board para matest ang circuit..... of course they have their own resistance values and wattage........

and one more thing Can anyone teach me how to wind wires in a transformer, I mean about transformer making, A step by step instruction, a video or pictures with guides would be of great help and I would appreciate it much......

thanks for the kind response in these simple forum, at baka if maperfect ko ang circuit design at matapos ko eto project ko eh magpost ako ng picture to serve as an inspiration and also to help everyone..........

I also welcome Coilgun enthusiast maybe we could teach one another with our own experienced and knowledge..... I'm glad for the replies....................
