any info for PSFB to DIY ?
attached are example not tested

I have SMPS with phase shifted PWM.
The PWM controller is UCC3895.
What controller you plan to use ??

Oo.. sorry i didn't notice you already mention that before.
If you need working unit you can contact me...
If you have assigmnent, task or project sure it will be faster if you reverse engineering from it.
48V 20A

2hartanto, thankyou in advance.
great if u can share me info for working unit, 960W PSFB driver is good to have a look.

i'll continue post progress on here

as DIY, this is the most complicated design that i ever done; high voltages; driver isolation; interface communication; MCU control; display units..etc
hope u can join in.

hi i used it,
but i cant make a fixed compansated FB loop , it make ringing
and on one leg (A,B leg) it can't make ZVC , but i think it was becuse of the fb loop,
do you know more abute the FB loop of this chip? is it current mode!
