Hello,
I would like to build a ultra (?) wide input range supply : from 90V to 1000V (50/60Hz and dc) with an output of 15V / 1A : i am wondering if it's possible to build this unit with only one flyback stage ? (in my opinion : very difficult, so i consider to use a 2 stages : one buck (possibly with pfc, build with a variable output : in=90Vac out=80Vdc (about), in=1000Vac, out=320V (about)) followed by a classic flyback).
Thanks for any advice.
