Basic knowledge of power adapters

Issue Time:2006-05-31
Today's mobile phones, computers and other electronic products are constantly updated in our lives, and this kind of electronic products have one thing in common is to charge them. The charging tool is the charger we are talking about now, and charging. There are also many types of devices, such as travel chargers, wireless chargers, solar chargers, USB chargers, etc. Various chargers are also convenient for our lives. I don’t know if I have encountered them. One situation is that the mobile phone can't be charged when it goes to the field, but someone else charges the charger after it has been charged. In fact, the charger is not the charger but the power adapter.

A power adapter, which is a small, easy-to-carry electronic device in life. This device provides the same parameters for a product that needs to be charged, that is, a power supply device that can be converted. The power adapter is generally composed of a casing, a power transformer, and a rectifier circuit. Moreover, the power adapter also has two output modes, generally the mode of the AC output and the DC output. Of course, there are different connection modes for different output discharges, and generally there are wall-mounted and desktop-type.

Nowadays, many laptops have power adapters that are used in 100-240V AC. Basically, many people buy laptops with external power supplies, but there are also a few power supplies that are placed in the mainframe. Many of the sales are travel power adapters, that is, you buy a nameplate on the power adapter, which indicates the power, current and some data, but also pay attention to the range of output voltage. If the mains supply for charging is only 110V, then That is, it can be used, but some parallel imports, without capacitive, will be burned in China's 220V mains voltage.
