Hello.
Thanks a lot for your help.

There seems to be no formula for obtaining Cclamp capacity in the document provided by TIDA-00951.
Could you tell me the formula to get Cclamp capacity?

Hi, Bae

The Cclamp is choosen using “acceptable” ripple voltage. For this design our designer set it to 8V.

Look at the equation 13 in below ariticle:

" Full-Bridge Isolated Current Fed Converter with Active Clamp" by Victor Yakushev, Valery Meleshin, and Simon Fraidlin.
