Thank you for the mail, I will see. About the power of the stun gun, I have to think about certain things, if that is very dangerous why not to use a firearm? ho ho ho!! JOKE!!! maybe you right, I donĀ“t know. Perhaps if I find the surge arrester build a stun gun as yours, maybe .... Anyway thank you very much buddy!!!

ANY commercial gun is not effective! Especially those with 9v batteries inside, because they can't give much POWER (in watts) to stop. In our country the output power for civilian stun guns is limited by law to 3 watts, but for law inforcement (police) it's 10 watts (feel the difference!). stungun.steelrats.net/Skorpion.html - i made one like that stungun.steelrats.net/ESHU200.html - another one, but working on EMD principle (low frequency, high pulse energy) That depends on which 9 volt battery you use. A 9 volt "Lithium" battery can supply a very good current. Possibly also a "Titanium" 9 volt battery, but I haven't tried one of these. Maybe they are not available in your country? What batterys do you use in those stun guns?

I've used simple 8 AA NiCd cells, because on that moment (about 3 years ago) i was unable to get anything better, not talking about lithium 9v which i can't get even now.

Ivan, Those Voltage Multipliers Only work with AC or PULSED DC. Not Constant DC.

If you want loud bright sparks simply connect an HV cap to an HV coil output. This trick is used in many low quality cheap china stun guns. They join 3-4 series connected ceramical caps in one block with HV coil, potted together.

Very practical, I want to know more of your circuit especially for 220V 50 Hz. Thanks.

Hi Lamazoid , you talk about this? No, capacitor should be connected in PARALLEL. Another way is to throw out everything after T1 and connect multiplier directly to it. But there's a risk of burning mosfets (i'm talking about my type of ciruit) due high voltage peaks. If you do so, i suggest to shunt them with TRANSIL diodes or zener at least. Or use high voltage mosfets like IRF 740, but performance will decrease. Optimal way is building another, flyback type converter for this.

Thanks lamazoid, summarizing ... , the capacitors must be soldiers in series with each other and all these capacitors in parallel with the HV coil . All right?

Yes, exactly. Be sure to use at least 3 caps for at least 10kv rated each.
