Marx generator core and Marx generator

Abstract

The invention provides a Marx generator core and a Marx generator, wherein thewhole Marx generator is ensured to be stable, reliable in establishment and compact in structure. The Marx generator corecomprises a first unit and a second unit. The first unit comprises N unit assemblies which are arranged side by side at intervals along a first straight line. The second unit comprises M unit assemblies which are arranged side by side at intervals along a second straight line. The first straight line is parallel to the second straight line. The N unit assemblies in the first unit and the M unit assemblies in the second unit are alternately connected in series to form a local S-shaped layout, so that the length of the whole Marx movement is greatly reduced. The layout of the whole Marx generator core is still in linear arrangement. An equivalent coaxial structure is formed between the Marx generator core and an external metal shell, so that a large stray capacitance to the ground is formed.The generation of overvoltage on an internal non-breakdown gas switch of the Marx generator is facilitated in the establishment process of the Marx generator. The working voltage range of the Marx generator is wider, and the establishment is more reliable and more stable.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a Marx generator core and a Marx generator. Background technique [0002] As a classic high-voltage pulse generator, the Marx generator has the advantages of simple structure, convenient operation and maintenance, low cost, and high energy transmission efficiency. It is widely used in high-energy physics experimental research and pulse power technology applications. The Marx generator is usually composed of multiple high-voltage capacitors and switches in series alternately. Its basic working principle is: the high-voltage DC power supply charges n (n is a positive integer) capacitors in parallel through the charging network, and the capacitors are isolated by switches; when The voltage on the capacitor reaches the preset value V 0 When the external trigger is used, the state of all switches inside the Marx generator is changed from off to on; the capacitor disch...

AI Technical Summary

Problems solved by technology

However, in order to achieve higher voltage level output under this structure, it is necessary to continuously increase the number of serially inserted unit components, which eventually leads to an increase in the length of the Marx generator core

Thus, a series of new problems that affect the working performance of the Marx generator are introduced, such as uneven charging and excessive inductance of the discharge circuit.
