The Research On High Voltage Pulse Power Supply And Its Application In Electrostatic Precipitation

In recent years,with the development of science and technology,environmental issues have become more and more prominent,especially air quality problems and water pollution problems,which have received increasing attention.The drawbacks of traditional processing methods are gradually revealed,and people are actively seeking new and efficient ways to deal with environmental issues.Pulse power technology is an electrophysical technology that stores energy and releases it to load in a short time to obtain high peak power output.Through high voltage pulse power supply,pulse power technology is applied in the field of environmental protection,which provides new ideas for water treatment and flue gas treatment,and has many advantages such as good treatment effect,high efficiency,no secondary pollution and so on.To this end,the research and application of high voltage pulse power supply is launched.This paper first introduces the development of pulse power technology and high voltage pulse power supply,and from the field of electrostatic precipitation,the influence of various parameters on the dust removal effect are explained in detail,which provides a basis for the parameter design of pulse power supply.Based on this,a high voltage pulse power supply circuit is designed and the key components in the circuit are selected.The circuit is simulated by MATLAB to verify the feasibility of the scheme.After that,the magnetic switch and RCD absorption circuit are used to solve the synchronous triggering problem,reliable shutdown problem and voltage spike problem,which lays a foundation for the reliable application of the circuit.Then the CST software is used to simulate the shielding effectiveness of the charger,which proves the stability of its operation in complex electromagnetic environment.The circuit is applied to the actual load and tested under the conditions of high repetition frequency and high DC base voltage.The reliability and operability of the high-voltage pulse power supply were verified by the actual processing results.Finally the production of high voltage pulse power supply is completed.
