Either way, personal attacks are expressly prohibited, and calling someone an arrogant twat is getting pretty close to a personal attack. |

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. --- End quote --- 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.

Back in the days of CRTs modules to do this we're widely available and inexpensive. I recall 4000 volts was one standard, which should be enough to operate many ionizers. I don't know why you have not been successful with this configuration. There are several traps, which I don't recall at the moment. I would again caution you to think carefully about working with these higher voltages. A new world again from the 600 volts of your three phase you are familiar with. Your chances of killing yourself are really pretty low, albeit higher than many are comfortable with. But the chances of a painful incident are pretty high. |

GadgetBoy - Please understand we get every level of skill posting on this forum - and the only way we can judge anyone's competence is by what is shared here. You could have spent 30 years in IC fabrication - but if you don't say anything, then you are not being fair if you shoot someone down for commenting about current limit of bond wires. As you will appreciate, when people start talking about 3 digit voltages and higher, most members here start treading carefully - as they should. If we don't know your background, we ARE going to be conservative and sometimes that will carry with it some strongly expressed opinion - just to make sure the significance of what is being said hits home. We cannot look over your shoulder, so our advice has to strongly err on the side of safety. We would rather know you were appropriately challenged about your intentions (based on what we know of you) than make assumptions about your skills and have you die as a result. We NOW know you have sufficient knowledge to understand the risks involved ... and I ask: If you were presented with someone with the same sort of questions and lack of background as you presented to us, would you have been any less diligent in responding with a safety and knowledge oriented approach? --- Quote --- AND you posted your question in a portion of the forum intended for beginners, which you are clearly not. --- End quote --- What is the definition of "Beginner"? Certainly, someone who has little or no experience in electronics qualifies, but I would suggest it is just as appropriate for someone who is not well versed in a particular strand. Take me for example. The apex of my experience with RF is being able to SWR in 27MHz CB radio antennae - so if I had an RF question, I'd be considering the Beginner's section for that. |
