An AC-DC controller is an electronic device that regulates and controls the conversion of alternating current (AC) power to direct current (DC) power. It plays a crucial role in power supply circuits, where it manages the process of converting high-voltage AC power from the mains into the low-voltage, regulated DC power required by various electronic devices.
