Research on Compact Nanosecond High-voltage Pulse Source

Abstract

Abstract With the application of pulse power technology in the fields of biomedical research, portable pulse source, and electromagnetic pulse radiation, the research of pulse sources puts forward new requirements such as compact structure, long pulse width, and high voltage resistance. The traditional pulse source has a long pulse period and short pulse width, which cannot meet the requirements of the high repetition frequency and high output power. In this paper, a nanosecond high-voltage pulse source is designed, which consists of a primary power supply, a pulse charging system, and a pulse shaping system. The DC power charges the Marx generator, while the Marx generator output is shaped by short-circuit sharpening switches. In this paper, PSpice simulation software is used to simulate the results: the pulse period is 1.4ns and the peak-to-peak voltage is 210kV.
