Compared with the traditional AC adapter power transformer and other forms of power supply, the switching power supply has many advantages:
1. Energy saving. The green power supply is the most widely used power supply in the switching power supply. Its efficiency can generally reach 85%, and the high quality can reach 95% or even higher, while the efficiency of the AC adapter power transformer is only 70% or lower. The single-unit energy efficiency of general household appliances and industrial electrical equipment in the United States is greater than 92%. The "Energy Star" of the United States has made very careful and very strict regulations on the efficiency of electronic ballasts, switching power supplies and household appliances. For example, the California Energy CEC standard currently implemented.
2. The switching power supply is small in size and light in weight. According to statistics, the weight of the 100W AC adapter power transformer is about 1200g and the volume reaches 350 square centimeters, while the 100W switching power supply weighs only 250g, and the open-type power supply is lighter, less than 1/4 of the AC power transformer.
3. The switching power supply has various protection functions and is not easily damaged. However, other power supplies have more short-circuit or short-circuit accidents due to their own reasons or improper use.
4. It is easy to change the output current and voltage, and it is stable and controllable.
5. According to people's requirements, various power supplies with special functions can be designed, such as digital power supplies, program remote power supplies, etc., to meet people's needs.
