Research on High Voltage Pulse Power Supply for Dielectric Block Discharge

As an important discharge plasma excitation source, the formed pulse discharge source has the advantages of high energy utilization efficiency and high plasma density. In this paper, a high voltage pulse power system based on four-level Marx generator was designed and verified the feasibility using Ltspice software, Physical test input voltage 300V output up to 1.15kV, Pulse transformer with a 1:10 load access ratio for boost, The four-stage Marx generator system achieves a stable pulse voltage superposition peak of 10.35kV and a rapid rising edge up to about 75ns, Pulse width of up to 1us, With an average power of 89.2%, There is obvious discharge plasma phenomenon after the access medium block discharge plate electrode, The design is suitable for the DBD discharge requirements, It provides new ideas and experimental basis for the application of high voltage pulse power supply in the field of DBD plasma.
