Desktop versus plug-in power adapters

Power adapter is divided into desktop and plug two types of wall, plug wall type power adapter is the body can be directly plugged in the plug board or socket on the use of the power adapter. The desktop power adapter is the power adapter that the ontology needs to be placed on the desktop. Another difference between a desktop power adapter and a plug-in power adapter is that a desktop power adapter requires an AC cable to connect to the mains (alternating current). Power adapter in security products, communi

Why the price difference of power adapter is so big?

There is often a customer response to say, the rated power of the same power adapter, why is the price gap on the market so large? Some power adapters even double? Once upon a time, 1 watt 1 yuan slogan rang throughout the power supply industry, and look at today, many 36W power adapter are in the price of 20 yuan, so really should be changed to 1 watt 50 cents? Look at the industry's high-end power adapter products from another Angle, although the price is also all the way down, but also close to the level of 1 watt 1 yuan, power adapter industry is really swallowed up by the price war?

Service life of the power adapter

About the service life of the power adapter, which is a concern of many consumers, so how long can the power adapter last? Whether the service life can be extended. Generally speaking, the service life of the power adapter is generally 2-3 years. Improper use of the adapter will directly affect the service life of the power adapter. Therefore, in my opinion, the service life of the power adapter is directly related to how we use it.

Reliability Design of Switching Power Supply

Switching power supply is the core part of various systems. The demand of switching power supply is increasing, and the demand of reliability is higher and higher. There are many factors involved in system reliability. At present, the main misunderstanding of people's understanding is that the reliability is attributed to the reliability of components and the process of manufacturing and assembly, ignoring the decisive role of system design and ambient temperature on the reliability.

Heating problem with normal operation of the power adapter

The function of the power adapter is to change the voltage. In the process of voltage transformation, a part of the electric energy needs to be consumed due to the loss. After the electric energy is converted into heat energy, a part of the heat energy is distributed to the surrounding environment through radiation, convection and conduction, and the other part is absorbed by itself, so that the temperature of the power adapter increases.

Analysis on the cause of abnormal sound of switching power transformer

The noise of the transformer is mainly due to the transformer's excitation component contains low-frequency oscillation, which makes the magnetic molecules of the magnetic core move under this low-frequency magnetic field and generate mechanical vibration, thus causing the vibration of the surrounding air. Since the audible frequency of the human ear is about 20Hz to 20kHz, if the vibration of the air is within this range, it will eventually be heard by the human ear.
