Here's a full and complex design tool for calculating the SMPS transformer based on a push-pull , half-bridge and full-bridge topology .
It has many pop-up tips to help you to use it and correctly paste the values.
I think that it'll be very useful for many of you , as for the beginners and so as for the guru of DIY.
Enjoy it !.

Thank you, boy. I suggest to add some calculator for output inductor design, and why not any for new topologies as quasi resonants. But is only a suggestion.
Good job.
Good job.
i think he already did that: choke inductance.
Q:flux density is calculated by the program , or do i have to input it myself?

Hi Osvaldo!
I'm not the author of the program , the author knows english a little🙂 , but has more knowledge in мagnetic materials.
It's the first translated prog.
The series consists of :
toroid (ironpowder , coolmu , etc) core inductor calc.
other core inductor calc.
booster
flyback
forward
and smth more🙂
The program limits the density refers to over values , such as freq. , material , & other. You can put only less density manually .
Well, thak you for sharing.
Another Q: the Rds on value is equivalent for the bank of mosfets ?
Or better yet, can you explain what does that value means?
Thank you.

Thank you for your patience, i am a noob in smps, and trying to build a push pull psu: 12v to +/-40VDC, using a R80 core from kaschke.
Considering that in reality we have multiple mosfets in paralel , is that value(Rds on) value still useful?
I mean: i input a value of 0.4mili-ohms , that value represents the Rds-on equivalent for the group of paralleled mosfets, correct?
Again, thank you for your patience and explications.

If the Rds is small enough it will affect only the efficiency a little🙂
As a whole Rds won't affect the basic calculations of the transformer.

I find some non linear increase in what core power is rated at given freq.
let's say, at 50k it has 2kw, at 55k it has 2.1k, but at 60k it jumps to over 3kw
for now, I can't be more specific... how is this possible?

Hi Luka !
What kind of core do you apply ? 3kW it's no joke 😕
And what is the supply ?
Can you provide a screenshot of your research ?

I will post in few hours, screen shots, so you will be able to see
no, its offline, etd59 and so on 😉

Here it is and I wonder if winging fill factor has something to do with it
