hi microsim,
thats only for half bridge .would appreciate if you add information for choosing wire guage for multiple strands to avoid skin effects ie for a given guage using multiple wires of higher guages.post a complete example of smps right from start to end.thanks for sharing
thanks

can you post the formula file as an "xls" file? some of us are still using MS Excel 2003
Here is the Converted sheet into Excel 2003, Hope it will work with you.
My Friend MicroSim,
As I had already reviewed it, I'm developing the power switch quasi resonant, but now I have two serious problems:
Its formula can be used with Quasi Resonant power supplies? if so how should I proceed to calculate the inductor and capacitor are in series with the transformer?
I need urgent help from you guys,
awaiting,
a hug to everyone,
Cleber

Be mindful of the voltage requirements for the resonant capacitor. I designed a 120/240Vac resonant SMPS with Vin max = 400Vdc due to voltage doubler when configured as 120V AC Input. That required a film capacitor with an AC voltage rating of 650 V. Considering temperature de-rating, a 1KVAC rating was more appropriate. This was not easy to find at a reasonable price so I used two 500Vac capacitors in series.

waiting for your reply
Here you go with the formula, I know that its not available on the web, even its easy.
Enjoy..
hi microsim,
thanks a lot but can you post the equations involved.i am getting difference in secondary turns.
primary is same as mine.
thanks
