Hi Mag

wow you are skyrocketing

just a small doubt

you said in your reply n0 612


"So we have actually 4 20uf caps all at 350v. Now disconnect them and put them in series. BAM we have 1400v in a 10uf cap."


If i put 4 caps of 20 uF at 35o volts in serie i get 1400 volts in 5 uF and not 10 uF or do i miss something ?

What is very interesting anyway is the fact that by multiplying the transfers the freewheeling effect maintain a very high efficiency

Will go on the test

good luck at all

Laurent.

hey Woopy

I just woke up for work. =]  Ill be back at lunch. I may have made an error there. I have to look it all over.

umm we start with 10uf and end the first stage with 20uf
we start with 20uf stage 2, end stage 2 at 40uf.
start stage 3 at 40uf, end at 80uf

1 80uf at 350v  =  4 20uf at 350      so 4 20uf at 350 in series =1400v
Yes,    We will be using all the caps in the circuit at stage 3.

Ok Good Luck woops, Ill be back later. =]  Just try it all for size. I think I have come up with an idea to eliminate the having to get them in series in the end, but we will be getting similar results. ;]  Will think on it and post later today.

Laurent,

You are correct about the value. You end up with 5uF at 1400V. How does that compare to the original cap(s) of 80uF at 350V?

.99

[Magluvin]

He guys

Your right   5uf

Ive not had much sleeps

But as I said last night, In my daze and confusion, I have a way to directly get the 80uf, all caps in parallell still to get it out..

At work  will be back after work


thanks for the correction..

I have to review last nights posts  there were so many.

ok  solved it  will present at lunch  =]   Reduced stages simpler   About 3 hours from now.  =]

Been tired, and the stages were getting to me.

Stay awake woopy, 3 hours
