adapter
Adapter is an interface converter, which can be an independent hardware interface device, allowing the hardware or electronic interface to be connected to other hardware or electronic interfaces, or it can be an information interface. For example: power adapter, tripod base adapter components, USB and serial port adapters, etc.
adapter
The role of the adapter
1. The conversion between serial and parallel data transmission is required.
2. cache the data.
3. The device driver that manages the adapter is installed in the computer's operating system.
4. Realize the Ethernet protocol.
The role of power adapter
1. The power adapter is a current conversion equipment system from the power source to the device and to the battery. In other words, if there is no power adapter, once the voltage is unstable, our computers, laptops, 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.
2. On the other hand, in addition to improving the safety performance of electrical appliances, it is a kind of protection for us. Just imagine if our electrical appliances do not have a power adapter, once the current is suddenly interrupted, it may cause Blasting or fire caused by electrical explosions or sparks is a great threat to our lives and health. It can be said that having a power adapter is equivalent to insurance for our household appliances.
3. Power adapters are widely used in consumer electronic products. Most of the output power provided is within 100 watts, and the market demand is growing rapidly. Such as electric bicycle battery chargers, small size LCD TVs, notebook computers, printers, DVD players and set-top boxes, etc. have applications.
What is the function and principle of the power adapter
The power adapter is also called an external power supply (switching power adapter), which is a power supply transformer for small portable electronic equipment and electronic appliances.
It is produced because in real life, electronic devices often cannot directly use household electricity, because the power supply voltage used in the home is 220 volts, and the general electronic products generally require a power supply voltage of 5 to 20 volts. about.
So the role of the power adapter is very important (module power supply), especially if you go to the United States and other countries, the voltage is different from ours, then you need a 220V to 110V transformer. With it, we can use these electronic products conveniently and safely. So, what is the role of the power adapter?
The composition and application of power adapter
Power adapters are commonly found in small electronic products such as mobile phones, LCD monitors and notebook computers. Generally composed of a shell, a power transformer and a rectifier circuit, according to its output type can be divided into AC output type and DC output type, according to the connection mode can be divided into wall type and desktop type.
Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps , Communications equipment, audio-visual products, security, computer cases, digital products and instruments and other fields, and in these fields have a role that cannot be ignored.
