Req: Ionizer circuit

[mizk_electro]

Hi ...

Anybody would like to share ionizer schematic & Tips how to make one ?

Some tips ...

If you are connecting it directly to the mains, try a voltage multiplier circuit. Google for "cockroft walton" multiplier and you will find the schematics.

0.1 microfarad capacitors of 600 volt rating and 1N4007 diodes can be used. You will need about fifty of each in order to get a potential of about seven kilovolts on 240 V mains (double that on 110 volts).

If you only have battery or dc supplies available you need an inverter to generate the requisite ac.

You need to insulate heavily and limit the output current using a string of high voltage resistors at the output. This last point is CRITICAL for SAFETY.

another way
u can use an 555 as astable at rate 10-15 khz and drive a power mosfet gate such irf450.
then use a primery winding of a transpulse in current way of drian-source with 12-15 volt power supply . so u have a 200-300 volt by di/dt in primery and with  sufficient secondary/primery raito about 300 u can give 9kv at secondary. so rectify the output by seies of 1n4007 diode( #10-15 ) and use a 10nf / 20kv capacitor in parallel and then follow with ten 10meg resistor for safty purpose.
u must beware about insulation of transpulse winding and other high voltage part.

dear mizk electro

One thing I would like you to consider on making a high voltage source; be in alert on  the construction and on running. I had couple of bad experience. Try to leave enough space between diodes and capacitors on the ladder or the secondary windings whichever  circuit you would like to go.

Take care.
