Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps , Communications equipment, audio-visual products, security, computer cases, digital products and instruments and other fields, and in these fields have a role that cannot be ignored. So what are the functions of the power adapter?
Generally speaking, the function of the power adapter is the transformer and the rectifier. Home AC power is 220v, and our computer uses DC 12v (as if it is), so we can be sure that the power adapter is a transformer and rectifier. The adapter is a transformer, so we should all know that AC 220v is transformed into a voltage through a transformer and transformed into a direct current through a rectifier. There is consumption here, and these consumption will be converted into heat, so it is normal for the power adapter to generate heat. The transformer is made of silicon steel sheets. After the transformer is energized, magnetic flux is generated. The magnetic flux will cause the silicon steel sheets to generate force and generate a buzzing sound. This is normal. However, the sound of overheated earth is abnormal due to many reasons: unstable AC voltage; chip damage; short circuit between turns; component damage and so on. By the way, the role of the adapter is an electronic product that converts alternating current into direct current.
