Switching power supply share with the characteristics of the power adapter

With the rapid development of modern science and technology, more types of power adapter and switching power supply, such as sequential, but the size of both the power adapter and switching power supply, shape differences, their internal structure and properties of usually doesn't happen too big change.

1, the switch power features:

Switching power supply are made by circuit control switch tube in the way of high speed and globe, provide the direct current into high frequency alternating current (ac) to variable voltage transformer, and help to produce one or more sets of voltage.

Turn huawei is the cause of the high frequency alternating current (ac) in high frequency ac transformer transformer circuit efficiency is higher than 50 hz a lot, so the switch transformer can do is very small, and the work is not very hot, very low cost. If not turn 50 hz into high frequency switching power supply, there is no meaning.

2, the characteristics of the power adapter:

Power adapter is power converter (both AC DC), by alternating current into direct current, then through the computer, it can't protect computer, but there is a storage power of computer storage (also called charger), so at the time of power outage can protect the computer.

Composite aircraft power adapter used in routers, phone, game consoles, the language repeater, walkman, laptops, mobile phones and other devices. Most of the power adapter can automatically detect the 100-240 v alternating current (50/60 hz).

Power adapter is a small portable electronic devices and electronic power supply power transformation equipment, its external power supply, and host connected by a line, so that we can reduce the volume and weight of the host, only a handful of the electricity supply of equipment and appliances built within the host.

Inside it is composed of power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output; According to the connection mode can be divided into the plug wall and desktop type. Have a nameplate on the power adapter, marked on the power, input and output voltage and power flow indicators, such as paying special attention to the input voltage range.

3, the difference between the power adapter and switching power supply

Switching power supply and adapter are switching power supply, are made of high frequency switch tube and its control circuit. The adapter power supply is a voltage switching power supply.
