Is a useful calculation

Anyway this is idea, after testing and building prototype I’ll post results.
WARNING: Do not get v tight gel attempt to do this at home, this uses live AC current and it can easily kill you!
Remember, I’m trained amateur and I know what I’m doing. ;)

Sounds like a challenge to me.  :) Seriously though, thanks for the infol. I'd love to make my own pulse charger.

Exactly right

This table for an indian designer and i found it different My Blog from all others
I ask if this colculation is correct or no and what is the equation he used to detremine the relation between transformer power and the core cross section area ?

the resulting voltages must also change by the same ratio, and this is true.

It is, but oron.com doesn't exists any more, so...
Fixed external link.

That link doesn't seem to work. Is your script still usable btw, Silvio? Or should I look for something else?

I find that best alternative is to buy standard (Polycrystalline) solar cells and create your own solar panel.
That way you have control of size, power and some other strange requirements.
One problem can be low production of partially shaded individual cells, in that case you can bypass load on them with diodes for balance.
Can increase production by adding aluminum passive cooler (or active water cooling), sun tracking, etc.

I'm really glad I found this test as I was planning to go with these cells. You saved me a lot of headache Silvio. What's the best alternative, though?

Don't know.
If you have tables for mains transformer, data are related to specific type of iron laminate sheet.
So you need to find out what type of material is used, and if there is defined specific dimension for transformer for this table.

Equation is: Power=(With * Height)2
With and height of core cross section are in cm, power is in Watts.
