A power adapter is a small portable electronic device that typically consists of a casing, transformer, rectifier circuit, filter circuit, voltage regulator circuit, and other components. Its design aims to ensure the safe and stable operation of electronic devices. Power adapters are widely used in various portable electronic devices, including but not limited to laptops, tablets, smartphones, digital cameras, game consoles, etc. These devices typically use built-in batteries for power supply, but the battery life is limited, so they need to be charged or powered through a power adapter connected to the grid.

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.
