EnglishPower supply is an indispensable thing in our lives. Whether it is electronic products or daily equipment, many places are inseparable from electricity. With the development of society, the electronics industry has developed a product called a power adapter. So what are the functions of this product and what advantages does it have?
First, the role of the power adapter
The power adapter is a current conversion device system between the power supply to the device and the battery to the battery. That is to say, if there is no power adapter, once the voltage is unstable, our computers, notebooks, TVs, etc. may be burned. Therefore, having a power adapter is a good protection for our household appliances, and it also improves the safety performance of the appliances.
On the other hand, in addition to improving the safety performance of electrical appliances, it is a kind of protection for us. Just imagine that if our electrical appliances do not have a power adapter, once the current is too large, it will suddenly interrupt, which may cause electrical explosions. Or the explosion or fire caused by sparks and other situations poses a great threat to our life and health. It can be said that having a power adapter is equivalent to insuring our household appliances.
Second, the advantages of the power adapter
Power adapters are widely used in consumer electronic products, and most of the output power provided is within 100 watts, and the market demand is growing rapidly. Such as electric bicycle battery chargers, small LCD TVs, notebook computers, printers, DVD players and set-top boxes, etc. have applications.
Most of the early power adapters used linear transformers. With the requirements of high efficiency and wide input voltage range for power adapters in consumer electronic products, and the increase of copper, iron and labor costs, most of the original linear transformers in such power adapters gradually Replaced by switching power supply.
In general, the function of the power adapter is to convert the high voltage of 220 volts in the home into a stable low voltage of about 5 volts to 20 volts that these electronic products can work, so that they can work normally. Without it, it will bring a lot of inconvenience to our daily use.
