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.
