What brands of switching power supply are there? Selection skills of switching power supply

Now many of our families will use switching power supply, which uses modern electronic technology to control the switching time ratio of the switch tube. Switching power supply is closely related to electricity consumption, and its quality must be excellent. It is an indispensable household appliance in modern home life. With the rapid development of power electronics technology, switching power supply products have been widely used, so which brands are there? The following small series will introduce it to you.

Switching power supply consists of four parts: main circuit, control circuit, detection circuit and auxiliary power supply. The main circuit includes five parts: pulse current limiting, input filtering, rectifier filtering, inverter and output rectifier and inverter. They protect the safety and normal operation of switching power supply, in which inverter is the core part of high frequency switching power supply. Everyone is familiar with switching power supply, which is widely used in life. The use of notebook computers is switching power supply.

Second, the switching power supply purchase skills

1, the output power of switching power supply is different. It is recommended that you choose a switching power supply with an output power of 25W-40W. This specification has the most stable voltage, good use effect and long service life.

2. Many product manufacturers are equipped with standard power supplies, and it is best to use these standard power supplies with standard size and output voltage. This kind of product is easy to buy, simple to use and maintain.

3. Before buying the switching power supply, please specify the input voltage range. For example, the common AC voltage specifications are 1 10V and 220V, so we should choose 1 10V and 220V AC switching power supplies. The general input voltage is AC: 85V-264V, and this specification can also be selected. Choose the voltage specification according to the use environment when purchasing.

4. Because the switching power supply will generate heat due to power consumption when working, attention should be paid to the heat dissipation of the switching power supply. Switching power supply has poor heat dissipation, easy damage and short service life.

5. The purchased products must have product certificate, so that the products are produced by regular manufacturers, and the quality and performance are guaranteed. Don't buy three-no products, otherwise the service life will be short and the equipment will be damaged.
