Abstract

The invention provides a charging circuit polarity automatic adjusting device, comprising a first diode, a second diode, a third diode, a fourth diode, a first input terminal, a second input terminal, a first output terminal and a second output terminal; the anode of the first diode is connected with the first input terminal and the cathode thereof is connected with the first output terminal; the anode of the second diode is connected with the second input terminal and the cathode thereof is connected with the first output terminal; the cathode of the third diode is connected with the first input terminal and the anode thereof is connected with the second output terminal; the cathode of the fourth diode is connected with the second input terminal and the anode thereof is connected with the second output terminal. The adjusting device can automatically adjust the polarity so as to lead the polarity of the charging power output terminal to match with the polarity of the charging circuit input terminal.

Description

technical field [0001] The invention relates to a device for adjusting the polarity of a charging circuit. Background technique [0002] At present, the two output terminals of the general charging power supply, such as solar charging power supply, have positive (+) and negative (-) polarities. When charging, connect the positive and negative output terminals to the positive and negative input terminals of the corresponding charging circuit respectively. After that, the battery connected to the charging circuit can be charged. [0003] Usually, there are signs indicating the positive and negative polarity at the positive and negative input terminals of the charging circuit to prevent the polarity of the charging power supply and the charging circuit from being reversed. However, due to mistakes or other external factors, the reverse connection may still occur, resulting in failure to charge the storage battery, and may even damage the charging circuit and the storage batter...
