Novel pulse formation network

Abstract

The invention discloses a novel pulse formation network, belongs to the technical field of pulse power, and is mainly used for generating a high-voltage pulse square wave. The novel pulse formation network is formed by sequentially connecting three stages of pulse capacitors in parallel, wherein an inductor is respectively connected between first output electrodes of each stage of pulse capacitor and the subsequent stage of pulse capacitor and between second output electrodes of each stage of pulse capacitor and the subsequent stage of pulse capacitor. According to the novel pulse formation network, a high-voltage pulse capacitor serves as an energy storage unit which has the advantage of high stored energy density; by the adoption of the non-uniform pulse formation network of a three-capacitor structure, the number of stages of the pulse formation network is decreased, pulse waveform regulation is facilitated, and fast-front quasi-pulse square wave output can be realized. The novel pulse formation network is compact in structure, small in size, high in voltage resistance, high in stored energy density and high in reliability, and can be applied to a hundred-nanosecond pulse power system.

Description

technical field [0001] The invention relates to a pulse forming network, in particular to a pulse forming network with a three-capacitor structure, which belongs to the technical field of pulse power and is mainly used for generating high-voltage pulse square waves. Background technique [0002] In the pulse power system, the pulse forming line is one of the important components. In the 1960s, J.C. Martin of the United Kingdom proposed the concept of using the forming line to obtain nanosecond high-voltage pulses. After decades of hard work, pulse forming lines have been successfully applied to various types of pulse power devices. However, the pulse forming line, which is a key component of a high-power pulse source, currently has the problem of large volume, which needs to be solved urgently. [0003] The pulse forming network is a centralized parameter loop that is connected in a certain way by several capacitors and inductors and can generate a square wave of a given wi...

AI Technical Summary

Problems solved by technology

Theoretical calculations show that the more the network stages of the LC loop, the more stable the pulse width, but in actual industrial applications, because the film capacitor pulse forming network is limited by the traditional film capacitor technology, it is bulky and heavy, while the ceramic capacitor pulse forming network is limited by ceramics. Due to the limitations of capacitor technology, short life, high impedance, low energy storage density, and poor reliability; so too many LC loops often cause the final pulse forming network to be huge in size, which cannot meet actual use

However, reducing the number of network stages in the LC loop cannot obtain ideal pulses. Therefore, it is of great significance to seek a pulse forming network with small volume, high voltage transmission efficiency, and large energy storage for the miniaturization and practical development of pulse power technology.
