[0002] A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a housing, a transformer, an inductor, a capacitor, a control IC, a PCB board and other components. Its working principle is to convert AC input into DC output; it can be divided into wall-mounted and desktop types according to the connection method. It is widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment. When electronic equipment is running at a high load, the temperature in the power adapter will rise sharply.
