Hello ,
When I examined the reference design, I noticed that there is a capacitor between PGND and GND, there is no other connection, it can provide a reference for reading mains voltages( so AC Voltage), but I think there is a mistake in this design regarding DC bus voltage reading. Neut-PGND is directly short-circuited, by the way.
What do you think about this issue? It does not seem right for the capacitor used to take a reference between two potentials when reading DC voltage.
Best Regards.
