Currently I am worked out with single phase full wave bridge rectifier. I am using the microcontroller to control the 4 SCR bridge.
I want to ask is how to ground the part? now have 2 part, one is the controller part, with the voltage have step down using transformer to 9Vrms. since the SCR bridge rectifier is using the 240V and the optoisolator is used to isolate the 240V and 9V part. Should I ground all both of the part together? or I also need to isolate the ground part?
