If the power adapter overheats, makes abnormal sounds or smells during use, it should be immediately stopped and after-sales service should be contacted for inspection and repair. To save energy and extend the battery life of electronic devices, it is recommended to unplug the power adapter promptly after the battery is fully charged to avoid prolonged charging. A power adapter is one of the indispensable accessories for modern electronic devices, providing stable and reliable power support for the equipment, allowing us to conveniently use these devices in various situations.

Input end: Receive external AC power.

Transformer: By using the principle of electromagnetic induction, the input voltage is transformed into a voltage suitable for subsequent circuit processing.

Rectification circuit: converts alternating current into pulsating direct current.

Filter circuit: Smooth and rectify the pulsating DC power to make it more stable.

Voltage regulator circuit: maintains the stability of the output voltage and prevents voltage fluctuations from causing damage to electronic devices.

Output end: Provides stable DC power to electronic devices.

Function

Voltage conversion: Convert the input AC voltage into the DC voltage required by electronic devices.

Current regulation: Provide appropriate current according to the needs of electronic devices to ensure normal operation without damage.

Power protection: It usually has functions such as overload protection, short circuit protection, and overheating protection to protect electronic devices from damage caused by power issues.

Power isolation: Isolate the input power supply from the output power supply to prevent current leakage or electromagnetic interference, and improve the safety and stability of electronic devices.

AC power adapter, also known as AC power converter or AC/DC converter, is an important power conversion device. Its main function is to convert AC power into DC power to meet the power supply needs of various electronic devices. An AC power adapter is an electronic device that receives AC input and converts it into a stable DC output through an internal conversion circuit.
