  Why is the power adapter making noise?(图1)

  Why does the power adapter make noise? And how is this noise produced? What is the reason for the noise? The following Senshuqiang power adapter manufacturers explain to you one by one.

  When the AC 220v is transformed through the transformer and transformed into DC through the rectifier, there is consumption here, and this consumption will be converted into heat, so it is normal for the power adapter to heat up. The transformer is made of silicon steel sheets. After the transformer is energized, a magnetic flux is generated, and the magnetic flux will cause a force between the silicon steel sheets, resulting in a humming sound, but this is normal. However, the excessively loud sound is not normal. There are many reasons for the noise of the power adapter, as follows:

  1. Short circuit between turns.

  2. Components are damaged.

  3. The AC voltage is unstable.

  4. The chip is damaged.
