AC-DC power supply circuits are one of the most common circuit configurations in electronic systems. Though designs may vary, the task of converting AC power to DC power is vital in the functioning of a great many electronic devices. Why is this? What is it about this kind of circuit that makes it such a necessary part of many electronic systems?
