Power adapter is widely used in various electrical appliances in our lives. This is a facility that can provide voltage conversion for electronic appliances and portable electronic devices. It can convert the high voltage of 220 volts in the home into general electronic products.
The required stable low voltage enables electronic products to work normally. Through such a device, people can make different electrical appliances get the most suitable voltage that they can adapt as power when they are in use. Moreover, this further ensures the safe use of electrical appliances and a long service life. If our electronic equipment is not equipped with a power adapter, once the voltage is unstable, our desktop computers, laptops, TVs, etc. may burn. Therefore, the power adapter is a good protection for our household appliances, and it also improves the safety performance of the appliances and extends the service life of the household appliances.
Some people may be worried about the heating of the power adapter, but don't worry. The role of the power adapter is the transformer and rectifier. Home AC power is 220v, and our computer uses DC 12v , so it is certain that the power adapter is a transformer and rectifier. Then the adapter is a transformer. 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.
