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

@ NerzhDishual

no problem, i also try to look in on the zon thread from time to time, too - i'll also have a look at that electrodes thread you mention too, thanks

i'm happy to post more info about the experiment if you'ld like - i didn't want to tire people with too much info, since there is already quite a lot of calcs, but i've been able to simplify the amount of measuring i've had to do because the output is now charging a cap then discharging it, so i can keep my calcs in energy form & compare directly with energy supplied

have you done any more experiments with your very cool-looking test cap-to-cap discharge rig?


@ Frederic2k1
good question - and very important!

you'll see that the values shown in my calcs for the two stacks of supercaps are 0.299F and 0.342F not the nominal value for 4x1F in series (0.25F)

the values shown were measured using the time taken to discharge to 37% from any preset voltage (the amount of discharge which takes one RC time constant) using a measured R for load resistor

Ok, when you have measured the time for one rc-constant exactly, then you are my hero .
I'm very happy, that you has verified the values

Hopefully you make some other experiments in future

@Nul-Points,

No, I have not made any more experiments with my caps.

You know what?
I tend to spread myself too thinly and little is achieved...
I'm interrested in a lot of things and this very forum is getting so huge that
I'm lost...

Best

@ND
i agree, it is difficult to stay focussed when there are so many interesting experiments going on

i find it is actually helpful to have one's own experiment(s) to maintain (from the French? 'to hold'?) a focus and follow up a related thread in OU.COM to which you can contribute some understanding and also,from time to time, look in on different threads which look interesting or perhaps are completely different to one's own interests just to learn something new maybe, or have a wider feel for what is going on elsewhere

your own experiments can give you some specialist knowledge and the rest of the forum can give you general knowledge

don't give up on those experiments!

@Nul-Points

you've got my attention with this one    I'd like to replicate your experiment with the
idea of confirming the results and adding in another couple of ideas I have. would you
say between your posts here and your website there is enough info to go parts shopping?
or have you learned enough now to suggest different components or values? if it's not
too much to ask could you post a suggested component list? thanks.
