The boost adjusting circuit is connected with a CHRG1 pin, a CHRG2 pin and a PROG pin of the control chip U2, and the nonlinear amplifying circuit is connected with the boost adjusting circuit, a a contact of the bidirectional switch S and a primary side inductance coil of the transformer T. The three-terminal voltage-stabilizing inverter power supply used for charging and based on the voltage detection circuit can eliminate or restrain interference surge in the output current, the ability of the three-terminal voltage-stabilizing inverter power supply to restrain the pulsation of the output current can be effectively improved, and the output current can keeps stable.

Description

technical field [0001] The invention relates to a charging power supply, in particular to a three-terminal stabilized voltage inverter power supply for charging based on a voltage detection circuit. Background technique [0002] Charging power rectifying device used for battery charging. In the early days, the AC motor-DC generator set, also known as the rotary unit, was used as the charging power source. After the 1960s, this charging power source was replaced by the charging power source composed of electronic devices. However, the existing charging power supply composed of electronic devices often adopts double transformers, which makes the cost of the charging power composed of electronic devices relatively high; the output power of the charging power composed of such electronic devices is also very low, resulting in poor load capacity; and, The existing charging power supply composed of electronic devices has poor ability to suppress output current pulsation, and has t...
