on the shelf (Wurth elektronik), you will find the model of the transformer used in this application note.
This is often what can cause problems when you are not equipped to make this type of transformer.

If you have any questions for validate your adaptation, post here.
For 20A you can buy...
Hello sabu31,
In the design of a Flyback transformer there are several criteria to consider before any decision on the options that will be taken.
We don't make the same decisions depending on whether you have a low voltage, a high voltage, several outputs, the power level.
Likewise, depending...
Slobodan Cuk's corrective commentary, which follows the initial article, is very correct and should be considered. There is often a gap between theory and practice, especially in terms of optimizing a Flyback design.
Hello,
here you have an interesting doc dealing with the different formulas:

Hi treez,
do you know MLX91206 from Melexis?
https://www.melexis.com/en/documents/documentation/datasheets/datasheet-mlx91206
It is a very simple circuit to use which allows to make a current measurement at low cost.
I use it to measure currents going well beyond 500A.
It costs significantly...
Hello ivan_mateo,
for helping you efficiently, could you please indicate more information about your project, like voltage output and power.
Is it for a DC supply or a battery charger?
Your input voltage is universal or US only?
Regards.
