# Is this DIY high voltage AC generator safe to use?

Making a DIY type high voltage AC power supply from 40 W soldering iron, 220 V AC to 12 or 6 V AC step down transformer and 5 A fuse. These things are ALL connected in series to the 220 V AC mains.

Am I doing this "high voltage AC generator" circuit right?

I am making a high voltage alternating current power supply of 10 - 15 kV enough to generate strong electrostatic influence on deionized water to construct a water bridge and investigate its physical properties for a research.

The circuit consists of a 40 W soldering iron (used as dummy load or sacrificial load in case the transformer fails), 5 A Fuse, and finally a step-down transformer of 220 VAC to 12 VAC or 6 VAC with center tap all connected in series to the AC mains 220 VAC

BTW I am at a beginner level when it comes to controlling high voltages.

• You should include a schematic as it is unclear how everything is connected. Sure you can describe it in text but that still does not show all the details. btw I am at a beginner level when it comes to controlling high voltages OK, so what could possibly go wrong then eh?

• Your question has so many wrong ideas that I would strongly suggest you do not start unless you have studied electricity and electronics a lot more: "step down in combination with 10-15kV high voltage". "Soldering iron as dummy load", a "step-down transformer of 220 V AC to 12 V AC or 6 V AC with center tap all connected in series" Feb 18 '19 at 13:28
• That 230 to 12 VAC transformer you found, you will saturate the transformer and effectivly short it. Also, if you don't know what you are doing, you need to stary far away from mains and/or high voltage! Feb 18 '19 at 13:35
• You will not get 10 - 15 kV from this, you will not. If the transformer would get 220 V AC as input (which it will not as the required current would be too high and the transformer would melt) you'd theoretically get 4 KV. But you will not because this will not work like that. High voltage is better left to the professionals. Feb 18 '19 at 13:44
• General rule: if you have to ask the question "is this safe?" the answer is no. Feb 18 '19 at 13:46
