Hi. New to building AC power supplies. I generally focus on digital circuits with DC.
However, I have a need for a 9V AC power supply, around 20VA. Obviously I can achieve this with a transformer, but do I need to regulate this to 9V, and if so, how? As I understand it, if the input voltage fluctuates, then so does the output.
TIA
