A charger refers to a device that converts electricity into electrical energy and transmits it through a cable to a battery or other electronic device for charging. It mainly consists of the following basic components.
1. Shell: The shell of a charger refers to the entire shell of the charger, which is generally made of plastic or metal materials and has the functions of fire prevention, waterproofing, and shock resistance.
2. Technical board: The technical board includes circuit boards and electronic components, and is the core part of the charger. The circuit board includes a DC stabilized power supply, control circuit, output regulation circuit, overvoltage and overcurrent protection circuit, etc., which can achieve stable current output and various protection functions.
3. Converter: The converter of a charger refers to a device that converts alternating current into direct current. It generally uses a high-frequency switching power supply, which has the advantages of high efficiency and power saving.
4. Button switch: A button switch is a device that controls the start and stop of a charger, usually including switches, indicator lights, etc.
5. Isolator: The isolator is designed to isolate the main circuit and external circuits, improving the safety of the charger. The isolator is implemented using insulating materials or transformers.
6. Output plug: An output plug, also known as a power plug, is an interface that outputs electrical energy to a battery or device.
7. Input plug: The input plug, also known as a power plug, is the interface for inserting an external power supply into the charger, usually a standard power plug.
In summary, the charger consists of basic components such as a casing, technical board, converter, button switch, isolator, output plug, and input plug. These components not only achieve current conversion and control, but also ensure the safety of the charger. In modern life, chargers have become essential electronic devices, such as mobile phone chargers, computer chargers, electric vehicle chargers, etc.
