Application of power adapter
Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments and meters, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD displays, LED lighting fixtures, communication equipment, audio-visual products, security, computer chassis, digital products and instruments, and other fields, And it plays an undeniable role in these fields. So what are the functions of power adapters?
The function of the power adapter
Generally speaking, the function of a power adapter is a transformer and rectifier. The AC power for household use is 220V, while the land used for our computer is 12V DC (as if it were), so it is certain 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 voltage through a transformer and DC through a rectifier. There is a consumption here, and these consumption will be converted into heat. Therefore, it is normal for the power adapter to generate heat. A transformer is made of silicon steel sheets. When the transformer is energized, magnetic flux is generated, which causes force between the silicon steel sheets to act, resulting in a buzzing sound. This is normal. But if the sound on the ground goes too far, it is abnormal for many reasons: the AC voltage is unstable; Chip damage; Interturn short circuit; Component damage, etc. By the way, the function of the adapter is to convert alternating current into direct current in electronic products.
