Teacher asked, I said that can improve power efficiency, there are small size and high efficiency characteristics. What else does it mean? For example, in the control of the characteristics of
High-frequency switching power supply of strong penetration, good adhesion, can effectively improve the deposition rate of the coating; flexible use, simple operation; protection function is complete;
High-frequency switching power supply has many advantages:
1, small size, light weight. Vintage 100 to tile electrical appliances, only the power part of the large power transformer has a few pounds of heavy, accounting for a large position of the chassis. While the switching power supply only a few hundred grams, a small piece of palm.
2, saving materials. The switching power supply saves a lot of copper and iron.
3, stable and reliable. Switching power supply has multiple protection measures, the traditional power supply is the basic fuse.
4, a wide range of voltage adjustment, easy to achieve a wide range of voltage adjustment, the traditional power can not be compared.
5, switching power supply energy efficiency is high.
6, switching power supply to eliminate the traditional power of nuisance 50 weeks of communication sound.
Switching power supply has so many advantages, has been more and more widely used to gradually replace the traditional power supply.
High-frequency switching power supply oscillation frequency is generally tens of KHZ, is relatively low 5050 in terms of ordinary frequency.
"High frequency" is the higher frequency, refers to the number of times per second oscillation to high-frequency switching power supply dedicated chip TL494, its reference oscillation frequency of 25KHZ, frequency than the traditional 50HZ power 500 times higher.
