Maybe you don’t know the power adapter, but when it comes to another name, everyone should be more familiar with it. It is an external power supply. It is actually a small portable electronic device and a power supply voltage conversion device for electronic appliances. 220 volts, the electronic equipment does not need such a high voltage. If you don’t use a power adapter, you can’t use all kinds of electronic equipment safely. Power adapters are needed on small electronic products like mobile phones, computers, routers, etc. we are most familiar with. , And industrial automation control, military equipment, communication equipment, power equipment, medical equipment and other fields also need power adapters, which are our guarantee for convenient and safe use of these electronic equipment.
Nowadays, there are more and more manufacturers of power adapters in China. In order to ensure that the quality of the power adapters they purchase is reliable, it is still necessary to choose products from professional manufacturers. You should notice that there is a nameplate on the power adapter. Indicators such as power, input and output voltage and current are indicated. When choosing a power adapter, you must pay special attention to whether the input voltage range is suitable for your electronic products. What are the characteristics of the power adapter? Let's take a look together now.
Power Adapter
The power adapter is small in size and light in weight. Because the power frequency transformer is not used in the switching power supply adapter, and the power dissipation on the switching MOS tube is greatly reduced, and the larger heat sink is omitted, the power adapter looks very small; The power adapter has low power consumption and high efficiency. Its frequency is generally above 50kHz, and in some advanced switching power supply circuits, it can be several hundred or nearly megaHz. This makes the power consumption of the switching MOS tube very small, and the efficiency of the power supply can reach 90%; the efficiency of the power adapter filter is high, so that the capacity and volume of the filter capacitor are reduced. The operating frequency of the switching power adapter is basically above 50kHz, which is more than 1000 times that of the linear stabilized power adapter, which increases the filtering efficiency after rectification by almost 1000 times. After half-wave rectification, capacitor filtering is added, and the efficiency is also improved. 500 times; wide voltage regulation range and good stability. Moreover, designers can also design different voltage stabilization methods according to the different needs of customers, and can provide customers with exclusive switching power supply integrated circuit chip solutions.
