Let's deep understanding of the power adapter and charger as the distinction and relationship

Let's deep understanding of the power adapter and charger as charger usually refers to the difference and relationship is a kind of converts alternating current to a low voltage dc equipment, its interior includes current limiting, such as pressure limiting meet charging control circuit, the characteristic of the power adapter is a transformer, rectifier and the voltage stability of power converter, the output is dc, in the case of meet the power can be understood as a low voltage stabilized voltage supply. Let's talk about the power adapter is what? What is the charger? What's the relationship and difference between each other. Charger: English name Charger, usually refers to a converts alternating current to a low voltage direct current (dc) of equipment, the Charger is dedicated for use by the rechargeable battery dc power supply, its interior includes current limit, limit pressure meet the charging characteristics of control circuit, etc. Charger it widely used in various fields, especially in the field of life is widely used in electric vehicles, the common appliances such as a flashlight. It is generally for battery charging directly, not through any intermediary equipment and devices. Processes of charger is: constant current constant voltage - a trickle, three hierarchical intelligent charging. Charging theory of three stages in the process of charging can greatly improve the battery charging efficiency, shorten the charging time, and can effectively extend the life of the battery. A three-stage charging use constant current charging, constant voltage charging again, finally USES the floating charge for maintenance. Generally divided into fast charging, charging up, a trickle charge three stages: stage of quick charge: with large current charging the battery to rapidly restore the battery power, charging rate can reach more than 1 c, the charging voltage is low, but it would limit the charging current within the scope of a certain value. Complement the charging stage: relative to the stage of fast charging, charging up stage and could be called slow charging stage. When, at the termination of the stage of quick charge battery has not fully enough, still need to join up the charging process, make up charging rate is generally not more than 0. 3 c, because the battery voltage was increased after a stage of fast charging, so make up the charging voltage charging stage should also be improved, and the constant within a certain range. Trickle charging stage: in the supplement charge late stage, when the detected temperature rose more than limit value or charging current decreases to a certain value, start with a smaller current charge until the end of satisfy certain conditions after charging. Power Adapter: English name Adapter, common on the market of the power Adapter is a transformer, rectifier and the voltage stability of power converter, the output is dc, in the case of meet the power can be understood as a low voltage stabilized voltage supply. Composite aircraft power adapter used in routers, phone, game consoles, the language repeater, walkman, laptops, mobile phones and other devices. Most of the power adapter can automatically detect 100 ~ 240 v alternating current (ac) ( 50/60Hz) 。 Power adapter is a small portable electronic devices and electronic power supply power transformation equipment, its external power supply, and host connected by a line, so that we can reduce the volume and weight of the host, only a handful of the electricity supply of equipment and appliances built within the host. Inside it is composed of power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output; According to the connection mode can be divided into the plug wall and desktop type. Have a nameplate on the power adapter, marked on the power, input and output voltage and power flow indicators, such as paying special attention to the input voltage range.
