Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing pulse forming module, such as excessive number of network nodes, short life, poor flat-top stability of the output waveform, serious waveform distortion of the pulse booster module, and decreased pulse amplitude. A high-voltage long-pulse-width quasi-square wave pulse generator has been developed. This device has the advantages of low cost, few network nodes, maintenance-free, long life and no distortion of pulse waveform, etc., and realizes high-voltage flat-top stability. Quasi-square wave pulse output with long pulse width, which can be used in high-power microwave, disinfection, food and wastewater treatment and other fields

Abstract

The invention relates to a quasi-square-wave pulse generator, specifically to a high-voltage long-pulse-width quasi-square-wave pulse generator, and belongs to the technical field of pulse power. The pulse generator consists of three parts, including a pulse formation module, a pulse voltage boosting module and a load, wherein the input end of the pulse formation module is connected with the output end of a primary energy storage system while the output end of the pulse formation module is connected with the input end of the pulse voltage boosting module; and the output end of the pulse voltage boosting module is connected with the load. The invention, aiming to overcome the shortcomings of an over large number of network nodes required by the pulse formation module, short service life, relatively poor output waveform flat stability, severe waveform distortion of the pulse voltage boosting module, low pulse voltage boosting ratio and the like by solving technical problems, provides the high-voltage long-pulse-width quasi-square-wave pulse generator; and the high-voltage long-pulse-width quasi-square-wave pulse generator has the advantages of relatively low cost, less network nodes, maintenance-free property, high pulse voltage boosting ratio, distortionless pulse waveform and the like, so that high-voltage long-pulse-width quasi-square-wave pulse output with high flat stability is realized.

Description

technical field [0001] The invention relates to a quasi-square wave pulse generator, in particular to a high-voltage long-pulse-width quasi-square wave pulse generator, belonging to the technical field of pulse power, mainly used for the generation of high-voltage quasi-square wave pulses, and can be applied to high Power microwave, disinfection, food and wastewater treatment and other fields. Background technique [0002] Pulse power technology originated in the early 1960s. With the development of many fields such as modern industry, agriculture, environmental protection, medicine, bioelectronics and national defense, research and development have high power, long pulse width, integrated compactness and long use The quasi-square wave pulse generator with characteristics such as lifetime is an important problem to be solved urgently. [0003] According to different energy storage types, pulse generators can be divided into inductive energy storage type and capacitive energ...
