I am building a Linear power supply for a project at school and the transformer I am using is centre tapped so that there is a split voltage of two 16 volt AC supplies if needed. I need a higher voltage of 28 Volts to supply an audio Amp IC (TDA7262) so I will not be using the split supply rather I will use the 32 Volt potential difference across the two 16 volt AC outputs.
I have found a rather simple circuit that looks like it will suffice. The difference is that the circuit i have found does not use a centre tapped transformer. So on the diagram i have attached i have drawn in where i believe the AC ground should go.
My question is:
Is that the correct way to ground my circuit, using the ac ground from the centre Tap? A rather simple question I know but I am just in two minds about it. I feel that there could be noise coming from the ground source, or is that non-true?
