A Transformer lamination thickness calculation

  1. May 3, 2016 #1
    I am trying to figure out the lamination thickness of a transformer to reduce eddy current loss at 10 MHz. I am new to the subject, any help will be appreciated. Also how do I calculate the size of a core to avoid saturation knowing the peak current applied to a 1:1 transformer. Thanks in advance

    Welcome to the PF.

    Iron cores and laminations are generally used at AC mains frequencies (50Hz, 60Hz), not at 10MHz. At 10MHz cores are commonly made of ferrite material.

    The datasheets for ferrite cores will give their Al ("A sub L") numbers to help you calculate the inductance you get for different numbers of turns. And saturation flux information will also be given in the datasheets.

    See TDK or other manufacturer websites for more information. :smile:
