Hello,
I need to design a 300W 48V->12V two-switch forward converter and I need to know how to properly calculate the two clamping diodes current ratings. They're only conducting the transformer magnetizing current (during the core reset phase) hence the question might be: is there any rule of thumb to aproximate the magnetizing current relative to the primary transformer curent (peak/average)?
Thank you very much for your time.
