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.
Transformer calculator (Public) / Is this colculation is correct for transformer ?

This table for an indian designer and i found it different 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 ?

please what is the Equation u use between the output power of the transformer and the cross section area of core ?

It is alive and I discussing here only about mains transformer design (50/60Hz), not particularly SMPS design.
Main reason is because I didn't work enough with SMPS to need such program to help me.
All programs which I create is to primarily help me in calculations and I publish most of them as free software to help others.

If somebody have knowledge and willing/time to help me I'm open to create calculator for any type of transformer design.

Hi, Sorry I'm a late comer for this forum. Even though this forum has minimal discussion page, it is very informative. I don't see any recent activities in this page and don't know this is still alive or not, but I have no idea about what program you are discussing about regarding the SMPS design.
I'm trying to design my very first flyback SMPS design and gathering information related to that. If any such software available to simplify my job, please share with me. For learning, all the design  I have to study and understand by myself, but if I can finish my design with a help of some softwares for the first time only, it will be a motivation for me to move further.

Thank you for your information that took me to read. It was very helpful to me.

Anyway this is idea, after testing and building prototype I’ll post results.
WARNING: Do not 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.
