Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] like figure 1 As shown, it is a schematic diagram of a fast charging system in an embodiment. The fast charging system 99 includes a mobile terminal 100 , an adapter 200 and a data cable 300 . The mobile terminal 100 and the adapter 200 are electrically connected through a data line 300 . The mobile terminal 100 includes a terminal connector 101 , and the adapter 200 includes a source connector 206 . Two ends of the data line 300 are electrically connected to the terminal connector 101 and the source connector 206 respectively.

Abstract

The invention discloses an adapter. A mobile terminal is charged through a data line, and a source end connector is used for receiving required charging voltage and required charging current from the mobile terminal. A control unit is used for obtaining the charging voltage and the charging current. The control unit is used for comparing the charging voltage and the charging current with the required charging voltage and the required charging current respectively, and a control signal is generated when the charging voltage and the charging current are different from the required charging voltage and the required charging current. A PWM (Pulse-Width Modulation) driving module is used for adjusting an output pulse signal according to the control signal so as to control the start frequency of a switch unit and change a third alternating current, and thus the charging voltage and the charging current are adjusted to the required charging voltage and the required charging current. In the charging process of the adapter, the adapter outputs voltage and current matched with the required charging voltage and the required charging current of the mobile terminal, and thus the charging effect of the mobile terminal is better.

Description

technical field [0001] The invention relates to the technical field of fast charging, in particular to an adapter. Background technique [0002] With the increasing power consumption of current mobile terminals, the capacity of their rechargeable batteries is also increasing. The traditional charging methods are facing problems such as low charging efficiency and long time-consuming. In order to solve the problem of slow charging, the introduction of fast charging method. [0003] The current fast charging method is to charge the rechargeable battery with a charging current of high current intensity. However, during the charging process, the charging current with high current intensity tends to cause the temperature of the rechargeable battery to be too high, and the high temperature will cause great damage to the rechargeable battery and the mobile terminal, thereby shortening the service life of the rechargeable battery and the mobile terminal.
