With the information given its impossible to advice you .

Hello Walkura
Thank you for reply ! but i can not upload my design (size = 10KB) because this note from site

The upload folder is full. Please try a smaller file and/or contact an administrator.

Maybe its the wrong file format to be allowed maximum attachment ize is 1024 Kb.
What i sometimes do when its the wrong fileformat is take a screenshot of the schema to make it jpg.
Also you should have a look at these 2 books i uploaded .

They give a step by step aproach on how to calculate and make inductors and transformers for most purposes .

Goodluck Walkura
