Abstract

The invention discloses a high-voltage pulse generator based on a pulse forming network and a varistor, and aims to solve the problems that the flatness of a pulse later-period waveform generated by an existing high-voltage pulse generator is lowered, and the energy waste is serious and the like. The high-voltage pulse generator is composed of a Marx generator, an MOV (Metal-Oxide Varistor) component, an inductor L1, a load Z, a discharge switch S1, and an LC filter branch; the LC filter branch is formed by connecting an inductor L2 and a capacitor C2 in parallel; the Marx generator, the L1 and the LC filter branch form two sections of pulses to form a network; the LC filter branch is connected between the Marx generator and the L1 in series; the L1 is connected between the LC filter branch and the MOV component in series; the S1 is connected between the Marx generator and the LC filter branch; and the Z, the MOV component and the Marx generator are connected in parallel. According tothe high-voltage pulse generator based on the pulse forming network and the varistor provided by the invention, a pulse forming line is not needed, a high-voltage pulse square wave with stable waveform flatness can be generated, and the energy utilization efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a high-voltage pulse generator in the technical field of high-power pulse driving sources, in particular to a high-voltage pulse generator composed of a piezoresistor and a pulse forming network. Background technique [0002] The high-power pulse drive source can generate nanosecond high-voltage pulses with accurate waveforms, and can compress the pulse energy on the time scale to obtain high-power pulse output in a very short time. In high-power pulse driving source technology, how to generate instantaneous pulses with accurate waveforms is very important. A basic approach is to use a Marx generator and a pulse-shaping line to generate the pulses. However, due to the huge size of the Marx generator and the pulse forming line, its practical application is limited. Therefore, miniaturization has always been one of the goals pursued by high-power pulse drive source technology. One of the basic ideas at present is to reduce the...
