AC-to-DC Supply Schematic of essential AC-to-DC control supply, appearing (from L-R) transformer, full-wave span rectifier, channel capacitor and resistor load. Some DC power supplies use AC mains power as a vitality source.
Such power supplies will now and then utilize a transformer to change over the info voltage to a higher or lower AC voltage. A rectifier is utilized to change over the transformer yield voltage to a fluctuating DC voltage, which thus is gone through an electronic channel to change over it to an unregulated DC voltage.
