Hi Team,
I received a question from customer on the purpose of diodes D100 and D101 in the PFC power stage schematic below. How do these diodes help in the AC sensing circuit?
Thanks!

Hi Logico,
D100 and D101 are there just to prevent the sensed voltage at the controller goes negative when line or neutral voltage goes negative.
