Hello everyone,
I was looking at the schematic (page 26) of a PSFB implemented by TI using the UCC28950 and I have seen two unusual things (unusual for me :roll which I do not understand their purpose.
Both of them are located at the output stage, after the SRs.
1st unusual thing: Why is there R8//R9 connected between the clamped voltage and the output voltage ?
2nd unusual thing: I do not see the purpose of C13 connected between the output stage and the input stage since there is no current flowing thorough it (it has no return path for the current).
Any comment is much appreciated !
Thank you for your time !
