Low-inductance Marx generator core and Marx generator

Abstract

The invention provides a low-inductance Marx generator core and a Marx generator in order to reduce the inductance of a discharge circuit of the Marx generator and ensure stable and reliable establishment of the discharge circuit. The Marx generator core comprises at least one generator unit assembly which is sequentially connected in series along the same straight line. Each generator unit assembly comprises a first capacitor unit, a multi-channel switch and a second capacitor unit which are connected in sequence. The first and second capacitor units have the same structure. The first capacitor unit comprises a first high-voltage plastic shell capacitor and a second high-voltage plastic shell capacitor which are connected in parallel. The multi-channel switch comprises at least two pathsof independent switch gaps, and all the switch gaps share one insulating closed shell. Each switch gap is connected with one electrode leading-out end of the adjacent high-voltage plastic shell capacitor through an electrode connecting piece. Every two adjacent generator unit assemblies are connected through the other electrode leading-out end of the adjacent high-voltage plastic shell capacitor.Compared with a conventional linear arrangement structure, the inductance of the discharge loop can be reduced by at least 1 / 2.

AI Technical Summary

Problems solved by technology

However, the formation of multi-channel switching is limited by the transit time of electromagnetic waves at the gap conduction position, and there is a large uncertainty

And the ability of the switch to form multiple channels is proportional to the size and number of its electrodes, and the excessive size and number of electrodes will lead to an increase in the inductance of the switch structure
