OU/COP>1 switched cap PS cct like Tesla's 'charge siphoning'

I'm having trouble even understanding how current could be stored in a capacitor. but...

I would think that the displacement current (from plate to plate) although having the potential to be of large magnitude, would be limited by the conduction current in the wires leading to the plates. An equal number of charges flow in from the wire and settle on the plates as does that which polarizes in the dielectric.

Come on .99 - the currents sum - per Maxwell.

Recently, I was working with a pulser of 10kv - two spark gaps, one main with magnetic quench, the other a sharpening gap.  Coax of arbitrary length before each gap, resistance on the first coax to control charge rate.  While tuning the gap, sometimes it would fail to fire, but the second coax, which is after the first gap, will still "jump" as it is "polarized?".  After the jumping coax, the discharge across the second gap was like a leakage of energy sizzling across the empty space of the gap.  Quite surreal actually.

No one that I have spoken to about this will tell me what is occurring.  If they know, they will not say.  I suspect that the impulse produced a displacement current that went through the second coax and left it polarized.  Coax is RG-58 and doesn't hold much more than 2kv very well, so 10kv is asking a little much of it.

I brought it up in this thread as there may be a way to deposit more energy in the cap than is consumed in the circuit.   Apologies to nul-points if I am pissing in his front yard.

LOL ...you call that pissing?

Sorry.  I do not know if you are being sarcastic or not.

If you believe my post are not helpful to your thread, then let me know and I will remove them.  I have already proved my suspicions to myself and have no deflated ego that requires me to prove them to anyone else.  I was just trying to share with others and your thread seemed like a good conduit for that.

Extra charge in a capacitor for free is good, but it stores energy not power, so charging a battery for free is a much better power source and you can charge batteries the same way. 

John Bedini actually charges enormous batteries with this method and they become more efficient at retaining the charged condition.  The way he explains it sucks, but the results are good.

Sure beats windmills and solar cells.

hi Grumpy

no sarcasm intended - was thinking more along the lines of the "that's not a knife, THIS is a knife" scene in Crocodile Dundee

Ivor Catt (inventor of the wafer-scale self-'repairing' memory chip back in the 80s?) had some interesting things to say about the nature of caps, co-ax, and transmission lines (TL)

seem to remember he used co-ax to demonstrate that a cap is a special case of a TL, in which case it's possible that a cap may not be the static mechanism generally thought, but instead the applied voltage could be continually being 'reflected' across each plate

also believe i read somewhere that a cap actually appears to charge in discrete micro-quantised steps - this would fit in with Catt's ideas as newly arriving 'charge' would sometimes get slightly 'opposed' by reflections of existing 'stored charge'

Catt sadly discredited by mainstream now, due to long-running dispute with EE establishment, but some ideas have been given credence by more open-minded physicists (cf Nigel Bryan Cook)

sorry - using my DPA at present & don't have access to my stored links & ref. library for more source details

wonder if the energy 'jump' effect you've seen in your co-ax 'cap' fits in at all with the TL energy 'reflection' ideas?

hope this was of some interest/relevance

all the best
