Hi,
By stepping H and continuously finding the delta B from H to “next H”, I have calculated the peak B of a PFC inductor as 0.25T. (as in excel attached)
Its 50 turns on a 77072A7 torroid from Mag-Inc.
I can’t find on the website where I can check this value….is it on this page?...

Peak current is 12.3A and switching frequency is 60kHz (it’s a 600W PFC with 100VAC input)
