Difference Between Power Adapter And Voltage Regulator
Jan 11, 2018

1, the power adapter is a small portable electronic equipment and electrical power supply conversion equipment, generally by the shell, power transformers and rectifier circuit composition, according to its output type can be divided into AC output type and DC output type. Straightforward can be understood as a voltage converter, such as converting 110-220 volts of alternating voltage to a fixed DC voltage.

2, voltage regulator is to make the output voltage stability equipment. Voltage regulator with constant voltage, control circuit, and servo motor components. When the input voltage or load changes, the control circuit sampling, comparison, amplification, and then drive the servo motor rotation, so that the position of the regulator carbon brush change, by automatically adjusting the coil turn ratio, so as to maintain the stability of output voltage.

The power adapter has a higher voltage without load if you take the load, you will find that its voltage will come down, this is due to its own limitations, only to provide a suitable voltage to the load, and the main function of the regulator is to stabilize, it will be through its voltage stability in a certain range, It has action over or below this value, and the power adapter has no effect. The two can be based on the use of the case to distinguish, if the load is not high requirements of the place can be substituted, but if the load on the power requirements are higher, even if the voltage changes are not 1V, then you must use the regulator, otherwise do not burn the load also to burn power.
