What is LED switching power supply?
2018-11-08 01:53:33
High frequency of LED switching power supply is the direction of its development. High frequency makes switching power supply miniaturized, and makes switching power supply enter a wider application field, especially in the high-tech field, which promotes the miniaturization and portability of high-tech products. 
In addition, the development and application of switching power supply are of great significance in energy saving, resource saving and environmental protection.
The electronic devices used in LED switching power supply are mainly LED diodes, IGBT and MOSFET. SCR has a few applications in input rectifier circuit and soft start circuit of switching power supply. GTR is difficult to drive and has low switching frequency. It is gradually replaced by IGBT and MOSFET.
