Abstract

The invention discloses an AC-DC rectifier, and the rectifier comprises an AC-DC rectifier module, a DC switch module, a DC transformer, a transformer secondary voltage selection module, an output voltage control module, an output sensing module and a main control module; the AC-DC rectifier module is used for rectifying input AC into DC, the DC switch module is used for shunting the DC so as to control the current input to the input end of the DC transformer, and the transformer secondary voltage selection module is used for regulating and controlling the output voltage of the DC transformer. The output voltage control module is used for outputting the output voltage of the transformer secondary voltage selection module to the DC transformer to enable the output voltage of the DC transformer to be a specified value, and the output sensing module is used for outputting the output voltage of the DC transformer to the rechargeable battery; the main control module is used for controlling the output voltage of the transformer secondary voltage selection module by detecting the voltage of the rechargeable battery; therefore, constant-current and constant-voltage charging of various battery packs with different voltages is realized.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to an AC-to-DC rectifier. Background technique [0002] The electric energy we use comes from the mains. The mains is an alternating current with a voltage of 200V~240V. When charging the rechargeable battery with the mains, the alternating current must be converted into direct current. Converted to direct current, when the voltage of the alternating current changes, the current and voltage of the direct current input to the rechargeable battery also change accordingly, such as Figure 4 As shown, only when the current and voltage of the input DC power of the rechargeable battery are kept at a constant current and constant voltage, the charging efficiency is the shortest and the charging efficiency is the highest. Efficiency, and it is also easy to cause damage to the life of the rechargeable battery. [0003] Therefore, under the situation that the application of charging equipme...
