What are the characteristics of power adapter and switching power supply?
The power adapter and switching power supply are different, including to the specifications, shape, size, precision density, performance and other parameters.

1. The use is also different. The power adapter is mainly suitable for small electrical appliances, electronic products, etc., while the switching power supply is to control the entire switch, which is suitable for all current-changing electronic equipment.
2. The characteristics of power adapter and switching power supply.
The characteristics of the switching power supply: through the circuit to control the switching tube for high-speed pass and cut off, the direct current is converted into high-frequency alternating current to provide the transformer, so as to generate one or more sets of voltages, which are converted into high-frequency alternating current. The reason is that the high-frequency alternating current changes in the transformer.

The efficiency in the voltage circuit is much higher than 50HZ, so the switching transformer can be made very small, and it is not very hot during operation, and the cost is very low, such as if 50HZ is not changed to high frequency, the switching power supply is meaningless. The characteristics of the power adapter: manufacturers are producing power converters (AC to DC), most of which are converted from alternating current to direct current, and then through the computer.

It cannot protect the computer, but there is a storage device (also called a charger) for storing power in the computer, so it can protect the computer in the event of a power failure.

Switching power supplies and power adapters are both switching power supplies, which are composed of high-frequency switching tubes and their control circuits. The power adapter is a voltage regulator switch the power supply. the switching power supply has a floating charge function, the voltage becomes larger as the current decreases, and then there is only voltage but no current.
