How To Distinguish Between Chargers And Power Adapters

  How to distinguish between chargers and power adapters

  Chargers usually refer to a device that converts alternating current into low-voltage direct current, which includes a current limiting, limiting voltage, etc. to meet the charging characteristics of the control circuit

  Power adapter is a transformer, rectifier and regulator power converter, the output is DC, in the case of power to meet the low voltage power supply can be understood.

  Chargers are widely used in various fields, especially in the field of life is widely used in electric vehicles, flashlights and other common appliances. It is generally a direct charge to the battery, not through any intermediary equipment and devices.

  The three-stage charging theory in the charging process can greatly improve the charging efficiency of the battery, shorten the charging time, and can effectively extend the battery life. Three-stage charge using the first constant current charging, and then constant voltage charging, and finally the use of floating charge maintenance charge.

  Generally divided into fast charging, make up the charge, trickle charge three stages:

  Fast charge stage: the battery with a large current charge to quickly restore the battery power, charging rate can reach more than 1C, then the charging voltage is low, but will limit the charge current within a certain range.

  Make up the charging phase: relative to the fast charging stage, make up the charging phase can be called slow charging stage. When the fast charging phase is terminated, the battery is not fully charged and the supplemental charging process is added. The charging rate is typically not more than 0.3C because the battery voltage is raised after the fast charging phase, so the charging voltage at the charging stage Should be promoted, and constant within a certain range.

  Trickle charge stage: At the end of the complementary charging phase, when a temperature rise is detected exceeding the limit value or the charge current is reduced to a certain value, charging is started with a smaller current until a certain condition is satisfied and the charge is terminated.

  Power adapter is widely used in routers, telephone sub-machine, game consoles, language repeaters, Walkman, notebooks, mobile phones and other equipment. Most of the power adapter can automatically detect 100 ~ 240V AC (50 / 60Hz).

  Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, it is external power supply, with a line and the host connection, which can reduce the size and weight of the host, only a very small number of devices and electrical power built in the host Inside.
