EnglishWith the rapid development of modern technology, more types of power adapters and switching power supplies are emerging, but no matter the size and shape of the power adapter or switching power supply, its internal structure and characteristics generally do not change much. The following power adapter manufacturers explain the characteristics of switching power supplies and power adapters.
1. the characteristics of switching power supply:
The switching power supply uses the circuit to control the switching tube for high-speed passage and cut-off, and converts direct current into high-frequency alternating current. .
2. Power adapter
Features: The power adapter is a power converter (AC to DC) that converts alternating current to direct current. After passing through the computer, the computer cannot be protected. However, the computer has a memory (also called a power adapter) inside to store power, so it protects the computer in the event of a power outage.
Power adapters are widely used in routers, main telephones, game consoles, language repeaters, Walkmans, notebook computers, mobile phones and other equipment. Most power adapters can auto detect 100--240V ac (50/60 hz).
The power adapter is a small portable electronic device and power conversion device for electronic appliances. It puts the power supply outside and connects it to the host with a wire, which can reduce the size and weight of the host. Only a few devices and power supplies are built into the host. .
It is composed of a power transformer and a rectifier circuit, and can be divided into AC output type and DC output type according to its output type; according to the connection method, it can be divided into wall-mounted type and desktop type. Each power adapter has a nameplate indicating power, input/output voltage and current, paying particular attention to the range of input voltage.
3. the difference between power adapter and switching power supply
Both switching power supplies and adapters are switching power supplies, which are composed of high-frequency switching tubes and their control circuits. The adapter power supply is a regulated switching power supply.
