Technical development direction of switching power supply

by:MOSO     2020-02-25
The development direction of switching power supply is high frequency, high reliability, low consumption, low noise, anti-interference and modularization. Since the key technology of light, small and thin switching power supply is high frequency, all major foreign switching power supply manufacturers are committed to simultaneously developing new high-intelligence components, especially improving the loss of secondary rectifier components, and in power ferrite (Mn? Zn) Increase science and technology * * in materials to improve high frequency and large flux density (Bs) High magnetic properties are obtained, and miniaturization of capacitors is also a key technology. The application of SMT technology has made great progress in switching power supply. Components are arranged on both sides of the circuit board to ensure light, small and thin switching power supply. The high frequency of switching power supply will inevitably carry out * * on the traditional PWM switching technology. The soft switching technology of ZVS and ZCS has become the mainstream technology of switching power supply, the working efficiency of the switching power supply is greatly improved. For High Reliability Index, American switching power supply manufacturers reduce the stress of devices by reducing operating current, junction temperature and other measures, thus greatly improving the reliability of products. Modularization is the general trend of the development of switching power supply. Modular power supply can be used to form a distributed power supply system, which can be designed as an N 1 redundant power supply system and realize capacity expansion in parallel mode. Aiming at the disadvantage of large operating noise of switching power supply, if the high-frequency noise is pursued alone, it will certainly increase, and the partial resonant conversion circuit technology can theoretically realize high frequency and reduce noise, however, there are still technical problems in the practical application of some resonant conversion technologies, so a lot of work is still needed in this field to make this technology practical. The continuous development of power electronics technology * * makes the switching power supply industry have broad development prospects. In order to speed up the development of China's switching power supply industry, we must take the road of technology * *, walk out of the road of joint development of production, study and research with Chinese characteristics, and contribute to the rapid development of China's national economy.
