Hi,
We designed a SCR driver for variable speed AC motor (split-phase AC fan motors). This board includes some control and thus uses a 24V power supply. The ground of this supply is linked to the ground plane of the control circuitry.
My question is : should I link this ground to the Earth conductor of the cable that brings the 120V/240V to the board, should I leave the supply floating in relation to the Earth, should I attach it with a capacitor, or any other way?
What is good practice in such a case?
Thanks,
