AC-DC converters are devices that are used in the day to day life and in settings as common as the house, the office suite and also in military installations. They are used for devices that need to be protected from voltage overload as well as the effects that may arise from un-regulated voltage.

The AC-DC converter is tasked with transforming direct current from one device to another the former of which is the device that is being protected from the power overload. The converter is able to use a semiconductor device that aids in transferring the voltage from one level to another. A feedback mechanism is thus developed that ensures the circuit continuously operates.

The AC-DC converter is able to take in low input voltages and in the process of doing this uses the least amount of power. This quality explains why they are in large use in both the domestic and commercial sectors for protection of electronic equipment.
