Dumb question

<< < (3/7) > >>

GadgetBoy:
What about something like this? A Walton Cockroft ionizer needs very little power, so I'm wondering if a mains step-up transformer is a bit overkill. I just don't know if the waveform on this will work for a WC multiplier (or if waveform even matters much).

The link doesn't work for me, but I don't understand your question.  If you are asking if you can use a Cockcroft-Walton multiplier (commonly called a voltage multiplier) to convert mains voltage to low current 600 volt DC then the answer is yes.  If you think you need 600 volts as the first step in generation of a much higher voltage then I recommend that you sit back and think some more.  You should understand the basic concept, insulation, spark gaps, field concentration and a number of other concepts better than you seem to before proceeding.

The explanation by james_s in reply #9 is the main reason why reversing the transformer won't work backwards and is very dangerous. However the level of understanding about basic electronics indicates you should not try anything that involves any high voltage until you gain the necessary knowledge.

Well, aren't you an arrogant twat. I'd already assumed the answer to be no, but I like confirming my conclusions on occasion.

Well, I live in Canada. North American voltage isn't high enough to make a WC ionizer work, even with an abundance of stages. I've been trying to come up with an economical way of doubling or more the mains voltage before putting it into the multiplier.

I've attached a picture of the eBay thing I tried to link earlier.
