Development direction of switching power supply

The high-frequency development of switch mode power supplies is the direction of their development. High frequency makes switch mode power supplies smaller and more widely used, especially in high-tech fields, which promotes the development of switch mode power supplies. Every year, with a growth rate of more than two digits, they are developing towards the direction of light, small, thin, low-noise, high reliability, and anti-interference. Switching power supplies can be divided into two categories: AC/DC and DC/DC. DC/DC converters have now been modularized, and the design technology and production process have been mature and standardized both domestically and internationally, and have been recognized by users. However, the modularity of AC/DC, due to its own characteristics, encounters complex technical and process manufacturing problems in the process of modularization. In addition, the development and use of switch mode power supplies are of great significance in energy conservation, resource conservation, and environmental protection SCR is rarely used in input rectifier circuits and soft start circuits of switching power supplies. GTR is difficult to drive and has low switching frequency, gradually being replaced by IGBT and MOSFET. The future development direction of switching power supply is high frequency, high reliability, low power consumption, low noise, anti-interference, and modularization.
