Your picture shows the Forward Converter.
this topology can't be half-bridge or full bridge.
this topology s calculated in my program Forward.

Thank you, but I can't find your program named Forward.
Could you provide a link for that program please ?

Starichok51 I found your Forward program !

I made this calculation for my power supply, using the program:

I need 4 secondaries, as you can see.
Are these results correct for my topology ( 4 secondaries will be used ) ?

I can't figure out how to calculate the value of the 4 filter inductor

большое спасибо !

No transfer of their programs, I will not do more.


I came to this forum to earn some money. But no one listed on purses single cent.

Please, Starichok51, could you accept Paypal ? If not, how could I contribute some money for you and your excellent contribution ?
Give precise instructions if you please.
I am located in Buenos Aires, Argentina, and part of my parents were Russian.
 
I am sorry...
and is there a possibility to send on WebMoney?

in the menu "About program" is the number of purse WebMoney for dollars.

OK Starichok51, I made some research here.
I fist subscribed to Webmoney, put almost all my personal data and got a subscription, made a SMS confirmation to my cellphone, and also email confirmation using E-NUM service.
They are asking now for a photograph and copy of my personal ID for somebody to authorize using my credit card to send the money, but as I can see, this will take time.
I am sorry, despite the online translator, there are some issues with the language that he translator can't fight. x-(
So it is not just press the button and done.

Until all this paperwork is done, I am a registered user but can't use my credit card.
Let me suggest something that would be easier from this side, we can give it a try, Western Union:
http://www.wu-store.net/western-union-russia-moskva.php
Please check if this could be good for you.
I've been told that this works in Russia, I don't know your actual location, if you please provide me this information.
Tomorrow is monday and if you can confirm that Western Union works in your location, I will give a local call to them and find if it works from here.
What do you think ?

Sorry if allready answered somewhere, but i have searched and searched without any good results.
There are some perfect calculators in here :D. But..... But I miss one thing.
If one like me have too many thumps to do the Windings "by hand". Where do You buy Your transformers ? I know of Flux, but the have a minimum order requirement of 300 units. And that is a bit to much for us. We might need 75 - 100/year maximum

Can you post a link for this core ? Starichok doesn't speak and understand english at all , using on-line translators cannot give much help in technical discussions . I'll translate to him and give an advise.:adoration:

Dimonis, you are very kindness!!...
Thanks on behalf of all of us in this forum!!
