Title: What are the limitations of this voltage multiplier?
Post by: nsled on April 28, 2023, 11:48:28 am
Digging through a shed this come up, what would you do with it?

It's a 3 stage full wave multiplier, constructed with 9 10KV 0.1uF caps and 12 10KV 1A diodes. I just checked the prices and it's about $400US worth of components.

What would this even be good for and what limitations does it have? I've looked at multipliers on youtube but they are always constructed with much smaller components.

Am I right in thinking this will be limited on the frequency it can be used at due to larger caps? What advantage do larger caps hold in this configuration? Does 10KV mean I can hook a 10KV neon transformer (for a bit shy of 60KV?) up to it or does the rating mean you should leave a margin below it?

I'd say that everything open and 10kV is in the category of don't ask or don't do.

To get more answers you must convince others that you're not about to kill your self.
Or at least nobody around is not keen to assist you.

It's a high voltage physics experiments.

Unless you can afford thick lexan for fixture, HV wire, new probes, etc then don't bother


The scary part is hearing about HV and cost put together. I would call it a cheap ass voltage multiplier


And uh before you use it, that thing should be super clean. Like detailed
