Abstract

High-voltage pulse power supplies with simple structures and high energy transmission efficiency are widely used in the field of electric pulse comminution. To achieve a pulse power supply with a simple structure and high energy transfer efficiency, this paper adopts the structure of a high-voltage pulse generator that combines resonant charging of a pulse transformer with a single-stage Marx generator, and it conducts simulation analysis and performance testing on this pulse power supply. A 10kV pulse transformer was developed, and tests showed its coupling coefficient to be 0.999. Pill fragmentation experiments were conducted using needle-needle electrodes. The results indicate that the average charging efficiency of the high-voltage pulse power supply is 89%; the output pulse voltage peak is 11.2kV, with a rise time of 20 ns. Through experiments, the pulse power supply developed in this paper successfully fragmented a 1.57mm thick pill with only a single pulse application.
