Hi, I learning smps design with help of tutorials. I found this book "Power Supplu Cookbook By Marty Brown". There is one example calculation for 65W smps construction. I try to understand the design & calculation, but now I need some help to understand this.
The Example file & datasheet of the (...)

The attached (LTspice sim and pdf schematic and excel design doc) show a DCM Full Bridge smps with
Vout = 400vdc
Pout = 100w
Fsw = 100khz
The actual exact leakage inductance value in the transformer plays a big part in the design calculation. This is because the secondary side transformer (...)

Hi guys first i want to tell that my english is not good because i'm from itay :)
my problem is calculating transformer details (primary and secondry turns)
i'm using this circuit:
HERE ARE THE PICTURES OF WAVEFORMS:

Is it important to use iron core ? why not an smps ? you need just 110 volts 50A ? right ? 5.5kW ? if yes , you can use a simple H bridge .

i want to winding my smps transformer.i have three kind of wire (.20 , .15 , .10) and EI25/19 core.and i going to make forward transformer with Pout=60(15 volt,4Amper)
and my frequency is 50Khz.could you tell me the calculation and how i can do it?

it is pretty simple . what are the specifications of your smps ? out put voltage and current and frequency of operation .
Thus i can help you as well .

I designed some smps transformer based on practical method. But the problem is if I change one turn +/- total performance changes a lot. I need the calculation method. Can anyone help me in this case please?

For designing power transformers using CRGO and low cost core, normally we use some simple formula which relates transformer cross sectional area, core permeability and some turns/volt etc. Such simple calculations are practically sufficient for our purpose.
Just like that is there any easy method for claculating (...)
