  The role of power adapter.power adapter wholesaler(图1)

  Generally speaking, the role of a power adapter is a transformer and a 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 will be generated. The magnetic flux will cause force action between the silicon steel sheets, resulting in a buzzing sound. This is normal. However, the sound of the overfire ground is abnormal. There are many reasons: 1. The AC voltage is unstable. 2. The chip is damaged. 3. Short circuit between turns. 4. The components are damaged and so on. By the way, the role of the adapter is an electronic product that converts alternating current into direct current.

  Power adapters with large space are generally built-in. Generally, the adapters are not small in size. Small-sized machines are external. In order to save space, it is also convenient to replace. Dangerous inside
