Hi,
I am new to design boards connected to the AC line. As in the attached picture, I have two boards:
I have connected to PE: the Chassis, the output ground of the flyback converter and the reference of the several inputs (analog and digital).
I did this last connection in order to avoid propagation of the incoming noise from the inputs on the GND of the MCU board.
Is it correct this approach? Or is it better to reference the output ground of the flyback converter?
Many thanks in advance,
Riccardo

- A POWER BOARD with a flyback converter and some triacs;
- A MCU BOARD with a microcontroller and some analog and digital input stages.
