    Difference and relationship between power adapter and charge
    Source : www.syrhjd.com/en Author : LYGO ELECTRIC Clicks : Releases Date : 2019-07-26 20:48
      Charger usually refers to a kind of equipment which converts AC to low voltage DC. It includes current limiting, voltage limiting and other control circuits to meet the charging characteristics. Power adapter is a power converter through voltage conversion, rectification and voltage stabilization, and the output is DC. It can be understood as a low voltage regulated power supply when the power is satisfied. Now let's talk about what the power adapter is. What is the charger? What is the relationship and difference between them?
      Charger: English name Charger, usually refers to a device that converts AC to low-voltage DC. Charger is a special DC power supply for rechargeable batteries. It includes current limiting, voltage limiting and other control circuits to meet the charging characteristics.
      Charger is widely used in various fields, especially in the field of life is widely used in electric vehicles, flashlights and other common electrical appliances. It usually charges batteries directly without any intermediary devices or devices.
    The process of charger is: constant current, constant voltage and trickle current, third-order intelligent charging. The three-stage charging theory in the charging process can greatly improve the charging efficiency, shorten the charging time and effectively prolong the battery life. Three-stage charging uses constant current charging, constant voltage charging, and floating charging for maintenance charging.

      Generally, it can be divided into three stages: fast charging, replenishment charging and trickle charging.
    Fast charging stage: High current is used to recharge the battery to recover the battery power quickly. The charging rate can reach more than 1C. At this time, the charging voltage is low, but the charging current will be limited within a certain range of values.
      The replenishment charging stage: Compared with the fast charging stage, the replenishment charging stage can also be called the slow charging stage. When the fast charging stage is terminated, the battery is not fully sufficient, and the process of replenishment charging needs to be added. The rate of replenishment charging generally does not exceed 0.3C. Because the voltage of the battery increases after the fast charging stage, the charging voltage of the replenishment charging stage should also be increased and kept within a certain range.
    Trickle current charging stage: In the later stage of the replenishment charging stage, when the temperature rise exceeds the limit value or the charging current decreases to a certain value, start charging with a smaller current until certain conditions are met and end charging.
      Power adapter: English name adapter, the common power adapter on the market is a power converter through voltage conversion, rectification and voltage stabilization, the output is DC, in the case of meeting the power can be understood as a low voltage regulated power supply.
      Power adapters are widely used in routers, telephone mothers, game consoles, language repeaters, walkman, notebooks, mobile phones and other devices. Most power adapters can automatically detect 100-240V AC (50/60Hz).
    Power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It connects the power supply with a line to the host, which can reduce the volume and weight of the host. Only a few devices and appliances have the power supply built in the host.
      It is composed of power transformer and rectifier circuit. According to its output type, it can be divided into AC output type and DC output type. According to the connection mode, it can be divided into plug-in type and desktop type. There is a nameplate on the power adapter, which indicates the power, input and output voltage, current and other indicators. Particular attention should be paid to the range of input voltage.
