Default SMPS transformer design tool (ver.4000)

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.

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.

Static Drain-to-Source On-Resistance of the mosfet , taken from the datasheet.

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.
