Application of power adapter

Wentong power adapter is widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps, communication equipment, audio-visual products, security, computer chassis, digital products and instruments, And it plays an important role in these fields. So what are the functions of power adapters?

Function of power adapter

Generally speaking, the function of power adapter is transformer and rectifier. Household AC is 220V, while our computer land is 12V DC (as if), so we can be sure that the power adapter is a transformer and rectifier. If the adapter is a transformer, we should all know that AC 220V is transformed into voltage through the transformer and DC through the rectifier. There is consumption here, and these consumption will be transformed into heat, so it is normal for the power adapter to heat up. The transformer is made of silicon steel sheet. After the transformer is powered on, magnetic flux will be generated, which will lead to the force action between silicon steel sheets, resulting in buzzing sound, which is normal. However, the sound of the earth is abnormal due to many reasons: the AC voltage is unstable; Chip damage; Turn to turn short circuit; Component damage, etc. By the way, the function of the adapter is to convert alternating current into direct current.
