Pulse voltage-multiplying generation device with repetition frequency

Abstract

The invention discloses a pulse voltage-multiplying generation device with repetition frequency. The pulse voltage-multiplying generation device comprises a pulse source, a magnetic compression circuit, a pulse transformer and a pulse multiplication cascading unit, wherein the pulse source is used for charging the magnetic compression circuit through an inductor, and the input pulse is compressed by the front edge of the magnetic compression circuit, then conveyed to the pulse transformer to be subjected to primary voltage-multiplying, and then conveyed into the pulse multiplication cascading unit to be subjected to secondary voltage-multiplying and front-edge compression. The pulse voltage-multiplying generation device provided by the invention can be used for carrying out primary pulse compression on an output pulse of the pulse transformer through the magnetic compression circuit and carrying out secondary voltage-multiplying and front-edge compression through the pulse multiplication cascading unit, thereby reducing the requirements on transformation rate and output voltage amplitude of the pulse transformer as well as the compression rate of magnetic compression, greatly reducing the magnetic core volumes and weights of the pulse transformer and the magnetic compression circuit and realizing system miniaturization and compactness.

AI Technical Summary

Problems solved by technology

There are two problems caused by the high transformation ratio: First, the high transformation ratio requires a small number of turns in the primary coil of the pulse transformer

However, the above-mentioned circuit has the following disadvantages: 1. The capacitor is charged through the resistor, and the charging time is very long, so repeated operation cannot be achieved.

2. The ball gap is used as the switch, and its insulation recovery time and electrode ablation also limit the repeated operation frequency of the whole system
