If I have a transformer feeding a power supply circuit on a pcb (rectifier, filter, regulators, etc), do I need a two wire or a three wire connector to accept the wires from the transformer.
On my breadboard: There are two wires coming from the transformer plugging into the top and bottom of a rectifier (4 diodes). I've then got a positive vdc on the right wire coming out the the rect. and a negative vdc coming out of the left wire from the rectifier. The circuitry on the other breadboard is grounded back to the left wire on the rectifier, and the supply voltage is coming from right wire. So the DC flows out the right side of the rect through the circuitry and then back in the left side of rectifier where it then flows back through the transformer to ground (the neutral wire of the transformer).
Is this right?
So if I have a pcb, do I need a two wire connector from the transformer only?
Or should I have a third ground connection that the circuit grounds/flows to?
