Five core functions that the power adapter can achieve.adapter manufacture(图1)

  Power adapters are widely used in residents' lives. From the voltage regulators in the 1980s to the current laptop chargers, they can be called power adapters. With the development of technology, the current power adapters are gradually getting smaller and smaller. The functions that can be provided have not changed. Here we introduce the five core functions that the power adapter can achieve.

  Before the introduction, it is necessary to clarify the principle of the power adapter. It is not much different from the switching power supply. It is mainly suitable for adjusting the input and output voltage and filtering and removing impurities. I will also make a brief introduction to the power adapter of the notebook here. Function description, the first is to adjust the input and output voltage, the power adapter of the notebook computer can cope with the voltage range of 100V-240V, that is, no matter where you are, the notebook computer can be plug and play, no power converter is required , Secondly, the output voltage is based on the size and capacity of the notebook, generally ranging from a few amperes to tens of amperes, but the specifications are still according to the larger the screen, the more power consumption; secondly, the power adapter will stabilize the current and filter Impurities, generally due to different wavelengths and power strengths, will cause certain voltage instability or more voltage clutter problems. The power adapter is positioned at 50-60HZ, which limits the current to a certain extent and provides it to the computer. More stable power supply; the third is to protect computer components. If there is no power adapter, plugging the notebook directly into the socket will burn the original and the battery. The main reason is the load and other problems, and the power adapter is to control the current at Within the power load required by the notebook, to ensure that it does not bring security risks due to the power load during normal use; fourth, it can protect the battery, which shunts and stabilizes the input voltage, and filters the impurities and clutter in the current. , to give the battery a stable voltage power, and it can also bear the problems of sudden power failure, such as the reverse of the battery voltage, which further ensures the service life of the battery.

  During use, the power adapter will also send current to the machine for use and battery charging by default. After the battery is fully charged, it will send a signal to the adapter through the charging current control device, thereby forming a power outage, which is also one of the functions of its power adapter; Finally, the power adapter can also help the notebook computer to cool down, and it will not cause a safety accident due to sudden power failure or other problems. The current provided by the voltage regulation can also be more convenient for the notebook computer to use. These five functions are realized by the power adapter. If the power supply is directly input, the notebook computer cannot be used normally.
