The most useful video I've ever watched on RUclips period

Thank bro

[@saulob.cavalcante]

Thank you very much for making the spreadsheet available, this is the only way I can do the calculations correctly. congratulations 👏

[@juanfwidlar86]

Excellent Video, a very easy tutorial for make and design pulse transformers, greetings from Mexico

[@LongTechnical]

Thank bro

[@gtcollection6933]

This is amazing knowledge sharing, thanks for that! Incredibly well explained and concise tutorial too. I bet a lot of us would like to see how to calculate a high-frequency flyback gap'ed core transformer (one with NP0, AUX and NS0). Looking forward your next videos, keep it up #subscribed!

[@PiotrK2022]

It's not... That transformer is dodggy, just one layer between pri. and sec. - that's a fucking joke... That transformer potentially may set his house on fire with so poor insulation between pri. and sec...

[@mariote1359]

Perfecto ya no tengo excusa para no terminar los proyectos que me salieron mal en las smps que hice esto lo facilita enormemente, muchas gracias, como siempre aquí mi like, saludos desde Mexico.

Thank you again. I Appreciate your great effort to share very important knowledge. Your example here uses half bridge topology, but, Can I use the excell program to the others topology, like push-pull or flyback? Thanks in advance.

This is diferent video. I never think so easy from dificult calculations.

[@sc0or]

Because it does not contain any parameters which depend on a magnetic material and an air gap. This works for a used double ER gapless transformer core from a computer PSU. Period. Just try to start calculating what YOU need (using your particular application), and you'll find it much complex.

[@yuribiktop6595]

Is the number of layers important?
Will this calculation table work with multiple outputs i.e 12v and 21v?

[@miqbalzidny]

Does this formula only apply to Half Bridge topology? What if I use push pull topology?

[@mikailtasar6613]

THANK's BROOOO 😍

[@sanjikaneki6226]

what limits the power transferred by the transformer? Also how do u know that u have enough inductance on the primary ?

Thanks a greatest information..sir plz tell about silicon ferrite core is how to made with complete Matel compassion

[@FinishTouch]

Thanks

[@alirezanamadmalan7878]

Hello Sir. Thanks for sharing! I think there is a sim-calculation, as you can see in the schematic you considered Vin as 310V while in formula you considered Vin=155. Both definitions should be defined separately. Thanks again

[@raphaelcoti692]

On the schem* the middle point is 155 V, this is unique to this half bridge topology

[@LongTechnical]

No bro

[@aqeelsoler]

Very good work .
Viche name this application name please

[@truonggiangsolutions9640]

please explain to me where the formula to calculate Ae
Ae=(d*d*3.14))/4
so if D=11.30
so the formula is Ae=(11.30*11.30*3.14)/4 right sir?
thank you

đúng vậy, D là đường kính, công thức tính diện tích là Ae= pi*R*R = pi*D*D/4 (trong đó R: bán kính, D: Đường kính) lưu ý: công thức trên tính theo đơn vị cm vuông, nên nhớ đổi đơn vị sang cm trước khi tính
