The application discloses a Marx high-
voltage pulse power supply based on a high-
gain boost type DC-
DC converter, and the circuit is composed of an input DC power supply, two
power switching tubes, a switching
inductor and a cascaded
Marx generator; the cascaded
Marx generator can be expanded to n levels, and can be used in application occasions requiring high-
voltage pulse power supplies, such as
cancer treatment in
medical treatment,
water treatment,
waste gas treatment, sterilization,
electron and
ion beam generation and acceleration, electrostatic dust removal and the like. Under the same working condition, the Marx high-
voltage pulse power supply can realize high-
gain pulses, and compared with the existing Marx high-
voltage pulse power supply, can realize lower
switching power loss and higher voltage
gain. Meanwhile, the Marx high-
voltage pulse power supply also has the advantages of simple topological structure, few modules, few electronic devices and low cost. Therefore, the Marx high-
voltage pulse power supply has important economic value and practical
engineering significance.
