[Abstract]:The traditional power frequency thyristor rectifier used in electrostatic dedusting industry is not only large in volume, serious in consumables and low in dust removal efficiency, but also has many disadvantages in traditional power supply. A new design scheme of high frequency switching power supply based on digital processing chip is presented in this paper. The new type of high frequency power supply not only reduces the volume but also greatly improves the dust removal efficiency, which is in line with the development direction and demand of dust removal industry. First of all, this paper gives a brief introduction to the working principle of electrostatic dusting, different kinds of power supply and electric field characteristics. The current determines the maximum output power and the inverter frequency of the high frequency switching power supply and designs the basic topology. Secondly, this paper introduces the hardware and software design of the new high frequency power supply system. In this paper, the advanced power electronic switch device IGBT is used as the core of power circuit design. The series resonance technology is used to realize the IGBT soft switch to meet the design requirements. The power supply control system introduced in this paper takes TMS320F28335 as the core, which mainly realizes the system security monitoring and signal processing control. It can guarantee the stability and rapidity of the system. Finally, through a series of experiments, the paper draws the conclusion that the power supply system meets the design requirements, and puts forward some areas and development directions to be improved in the design.
