Power Adapter Transformation Equipment
Power Adapter Transformation equipment
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 carry the power adapter, that is, People often say 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, the power adapter is a small portable electronic equipment and electronic appliances 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, 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 to sample, compare, zoom, and then drive the servo motor rotation, so that the regulator carbon brush position changes, by automatically adjusting the coil turns ratio, thus maintaining the output voltage stability.
The power adapter in the case of no load voltage 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 function 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. The two can be differentiated 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. The composition of the power adapter is divided into three parts: the machine shell, the power transformer and the rectifier circuit. The AC output type and the DC output type are two types of output types. The connection mode is composed of two types: wall type and desktop power adapter. It is basically suitable for all electronic devices such as: notebook computers, mobile phones, home IT, and so on. Notebooks, mobile phones and flat-panel digital products require power adapter to power. So, why some mobile phones and flat-panel adapter can be generic, some can not it? When our laptop power adapter is damaged, is it necessary to buy expensive originals?
Switch-type power supply is the most common and most common form of power adapter used in our daily life. The most interchangeable power supply we use is the technology of modern electronics, which determines the ratio of the time that the switch is opened. Steady to maintain the balance of the output voltage of a power supply. Power adapter switching power supply works by means of pulse width modulation to control the IC and MOSFET to work, it has the advantage of its conversion efficiency is particularly high, its size is very small and easy to carry, the required voltage Wide range Its shortcomings is that when there is a problem or failure when there is a great difficulty in repair, but also on the power circuit also has some interference.
