Problems solved by technology
[0002] The electric energy we use comes from the mains, which is an alternating current with a voltage of 200V to 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 DC power input to the rechargeable battery is kept at a constant current and constant voltage, the charging time is the shortest and the charging efficiency is the highest. efficiency, but also prone to damage to the life of the rechargeable battery

The invention discloses an AC-DC rectifier with multiple voltage class outputs. The AC-DC rectifier comprises an AC-DC rectification module, a DC switch module, a DC transformer, an output voltage selection module, an output sensing module and a main control module; the AC-DC rectification module is used for rectifying an input alternating current into a direct current, the DC switch module is used for shunting the direct current so as to control the current input to the input end of the DC transformer, and the DC transformer is used for converting a voltage of the direct current input from the input end of the DC transformer into various voltage grades. The main control module detects the voltage of the rechargeable battery to control the output voltage selection module to select the voltage output by the DC transformer as a specified voltage grade, and the output sensing module is used for outputting the voltage grade selected by the output voltage selection module to 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 with multiple voltage level outputs. 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...
