  With smart devices occupying an increasingly important position in people's lives, with the gradual increase of functions, the problem of power consumption of the devices is gradually exposed, and people are increasingly becoming accustomed to carrying power adapters with them. People often say chargers. What is the difference between this power adapter and regulator?

   It was found that without a load, the voltage of the power adapter was higher than what he had marked, and the regulator was always this value. So what's the difference between these two?

   Difference between power adapter and voltage regulator

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

   2. The regulator is a device that stabilizes the output voltage. The voltage regulator has a constant voltage, a constant voltage, a control circuit, and a 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 is changed, and the output voltage is maintained by automatically adjusting the turns ratio of the coil.

    The voltage of the power adaptor is higher under no load condition. If you connect the load, you will find that the voltage will drop. This is due to its own limited effect, just to provide a suitable voltage to the load. The main function of the regulator is to regulate the voltage. It will stabilize the voltage passing through it to a certain extent. Above or below this value, it has an action. The power adapter has no such effect. These two can be distinguished according to the use situation. If it is in a place where the load power supply is not high enough, they can be used interchangeably. However, if the load has relatively high power requirements, even if the 1V voltage change will not work, a voltage regulator must be used. , otherwise burn the power without burning the load.
