Significance of research on high voltage switching power supply

High voltage power supply technology involves the field of high voltage engineering and power electronics technology, and it is developing towards digital and high density. Different from the general low-voltage DC power supply, the domestic high-voltage power supply has not yet formed a series and large-scale production, especially the development of ultra-large power high-voltage power supply, the huge market potential remains to be tapped.

The study of high pressure engineering at home and abroad has always been an important subject. High voltage engineering technology includes high voltage technology in power transmission and transformation and high voltage technology in electric field physical device, DC high voltage power supply belongs to the latter. The output power and output voltage of DC high-voltage power supply are constantly increasing, while the device size is constantly decreasing, and it has been widely used in high-tech fields such as controlled nuclear fusion, high-current electron acceleration, high-power microwave and free electron laser. Moreover, the latest power electronics technology has been applied to high-voltage power supplies, and foreign high-voltage power supplies with high power density have become series and scale production.

The miniaturization and program control requirements of high-voltage power supplies continue to improve, and it is an indisputable fact that new power electronics technology is used in the field of high-voltage power supplies. The development of high-voltage switching power supply to the three requirements, that is, the requirements of "generalization, serialization, standardization", the use of tends to be flexible, and it can be set up by software or hardware combination to adapt to different working environments and task needs. The use of switching inverter technology can make the high-voltage power supply have the characteristics of modular equipment, that is, the high-voltage switching power supply has the characteristics of reconfigurability, scalability, upgradability and so on.
