  The difference between a power adapter and a voltage regulator(图1)

  As smart devices play an increasingly important role in people's lives, with the gradual increase in functions, the problem of device power consumption is gradually exposed, and people are becoming more and more accustomed to carrying power adapters with them, that is, The charger that people often say. What is the difference between this power adapter and a voltage regulator? This article will introduce to you.

  It is found that when there is no load, the voltage of the power adapter is higher than the value he marked, and the voltage regulator has always been this value. So is there any difference between the two?

  The difference between a power adapter and a voltage regulator

  1. The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type. It can be directly understood as a voltage converter, such as converting an AC voltage of 110-220 volts into a fixed DC voltage.

  2. The voltage stabilizer is a device that stabilizes the output voltage. The voltage stabilizer is composed of voltage stabilizer and constant voltage, control circuit, and servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison and amplification, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the coil turns ratio is automatically adjusted to maintain the stability of the output voltage.

  The voltage of the power adapter is higher when there is no load. If you connect the load, you will find that its voltage will drop. This is due to its own function, just to provide a suitable voltage to the load. , and the main function of the voltage stabilizer is to stabilize the voltage, it will stabilize the voltage passing through it to a certain range, and it will act when it exceeds or falls below this value, and the power adapter has no such effect. These two can be distinguished according to the usage conditions. If the load power requirements are not high, they can substitute for each other, but if the load has high power requirements, even if the voltage change of 1V is not enough, then a voltage regulator must be used. , otherwise the power supply will be burned without burning the load.
