Are power adapters important for electronics?

Stability of the power adapter is always beneficial for electronic equipment, but a stable power adapter must be added. If the output power of the stable power adapter is required to be large and the performance is good, the price is more expensive. Therefore, for most of the power equipment with high power and low demand for Power Supply quality, the solution is often to improve the power supply quality of the power grid. Stable power adapters are mostly used in electronic equipment and instruments such as TV sets, electronic computers and their interfaces, that is to say, there is a dc stabilized power adapter in the equipment. Stable power adapter has become an indispensable part of electronic equipment. If the ac power supply quality does not meet the requirements, the ac stabilized power supply adapter must be configured in addition to the dc stabilized power supply adapter. The voltage of the ac power adapter is stabilized in advance before the dc voltage is stabilized.

The basic requirements of electrical equipment to the power adapter is that the output voltage or output current of the power adapter should be stable. In addition, different electrical equipment have their own special requirements, generally there are the following:

(l) small size, light weight. Now, with the development of large-scale integrated circuits (lsi), the size of the electronic devices themselves is shrinking, so the size of the power adapter needs to be small to match it. In particular, portable electronic equipment, must require its power adapter small size, light weight.

(2) the output of the power adapter is uninterruptible. With the increasing popularity of microcomputer application and the continuous development of processing technology, more and more strict requirements are put forward for high quality power supply. Interruption of power supply during the operation of a microcomputer will result in the loss of data in ram and the destruction of programs. Therefore, it is required that when the instantaneous power outage occurs, the power supply can be resupplied within an interval of less than 10 ms. Power adapter output is also required for unattended electronic equipment such as communications equipment.

Without stable power adapter support, no matter how good the configuration of electronic products, performance can not play. And want to get steady power support, good quality power supply is essential. Therefore, the power adapter is extremely important for the entire system.
