The charging principle of the charger is to convert electrical energy into DC electrical energy using an AC power source, control the current within a certain range through circuit control, and then output it to the charging device to supplement electrical energy for the device.
The core component of the charger is a converter, which can convert AC power into DC power, while also controlling the size of the output current to avoid overload and overheating. A converter usually consists of three parts: an input circuit, an output circuit, and a control circuit.
The main purpose of the input circuit is to reduce the voltage of a 220V AC power supply to a suitable voltage through a transformer, and convert the AC power into DC power through a rectifier circuit, which is ultimately transmitted to the output circuit.
The output circuit mainly controls the magnitude of the output current and the stability of the voltage, which can be adjusted through current adjusting elements in the circuit according to different equipment needs.
The control circuit can be designed according to the type of charger and battery, which can be constant current charging or constant voltage charging. The output current and voltage stability are controlled through feedback signals in the output circuit.
In summary, the charging principle of the charger is to control the voltage of the input power supply and the current and voltage of the output power supply through a converter, in order to quickly supplement electrical energy for the device.
