Research on the Direct Current Support Technology of Inverter Against Shock
With the vigorous development of modern society,people's lives and social production need to use a lot of electricity.In particular,continuous production enterprises such as chemical industry and metallurgy require uninterrupted power supply in their production process to provide continuous current for the technological process of production activities.Inverter plays an important role in industrial production.It can control the speed of mechanical equipment by adjusting the frequency of power supply,and meet the speed regulation requirements of different equipment in the production process.Short-term fluctuation of system voltage will lead to voltage loss and shutdown of frequency converter,and then the whole production line will be shut down,which will bring serious economic losses to production enterprises.Therefore,it is of certain practical significance to strengthen the anti-sloshing of frequency converter.Through kinetic energy buffering technology and direct current support technology,the anti-sloshing of inverter can provide stable current for the production activities of enterprises,ensure the safety of power equipment and help improve the economic benefits of production enterprises.By analyzing the direct current support technology route of inverter anti-sloshing,the application principle,advantages and disadvantages of Boost technology,high frequency transformer technology and thyristor technology are studied.
