Power Adapter What Is The Difference With The Regulator

Shenzhen GEO Technology Co.,Ltd | Updated: May 15, 2017

What is the difference between a power adapter and a voltage regulator?

With the intelligent equipment in people's lives occupy an increasingly important position, with the function of the gradual increase in equipment, power consumption problems are gradually exposed, people are increasingly accustomed to carrying the power adapter, that is, People often say that the charger. What is the difference between this power adapter and the regulator? This article will be introduced for everyone.

Found that in the absence of load, the power adapter voltage is higher than the value of his logo, and the regulator is always the value. So what is the difference between the two?

The difference between the power adapter and the regulator

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

2, Power Adapter the regulator is to stabilize the output voltage of the device. Regulator with constant voltage regulator, control circuit, and servo motor and other components. When the input voltage or load changes, the control circuit for sampling, comparison, amplification, and then drive the servo motor rotation, so that the regulator carbon brush position changes, by automatically adjust the coil turns ratio, thus maintaining the output voltage stability.

Power Adapter The voltage of the in the case of no load is higher, if you pick up the load will find its voltage will come down, it is due to its own role is limited, just to provide a suitable voltage to the load , And the main role of the regulator is the regulator, it will be through its voltage stability in a certain range, more or less than this value it has action, the power adapter will not have this effect. These two can be distinguished according to the use of the situation, if it is in the load power requirements are not high places can be used with each other, but if the load on the power requirements are relatively high, even if the 1V voltage changes are not OK, then you must use the regulator , Otherwise do not burn the load also burn power.
