AC至DC电源

AC to DC power supply is used to convert the alternating current to direct current. The AC to DC power supplies are used in applications where power needs to be processed from the AC power mains to loads requiring a fixed or variable DC voltage or current. This device consists of an electronic circuit with many components such as transformers (used to step the AC Voltage level up or down), rectifiers (used to convert AC Sinewave to pulsating DC wave), filters (used to remove the pulsation from DC wave and produce a constant current), regulators (help in maintaining the fixed output voltage).
