    Push-Pull center tap converter transformer design

    Thank you very much for your help. I have a few more questions. Which datasheet did you get some values about core? I found one, but there is no information about Bmax. Other subject; which wire size should I use to wind transformer? maybe firtsly I have to calculate current capacity or skin...

    Push-Pull center tap converter transformer design

    Ok so I calculated my transformer, need your opinion ! My need is a 12 VDC -> 250VDC, 500 W push-pull converter, oprating frequency 55 KHz. But I want to use multiple transformers, primary in parallel and secondary in serie. I will try to obtain 600W with 2 ETD49 transformer, N87 material, and...
