Abstract

The invention relates to a multistage inductive energy storage type pulse power supply and a power supply method. The multistage inductive energy storage type pulse power supply comprises n power supply modules, wherein the power supply modules are used for supplying power for a Load, circuit structures of the power supply modules are the same, and the power supply modules are mutually in parallelconnection; each power supply module is of a STRETCH meat grinder topological structure; furthermore, the n power supply modules share a same current conversion capacitor C. According to the multistage inductive energy storage type pulse power supply, the plurality of power supply modules are in parallel connection to provide sufficient energy for railgun launching; all the power supply modules are triggered at the same time, so that the mutual charging phenomenon among the modules is avoided; the power supply circuits and the Load are separated, so that power supply reliability and power usesafety are improved; all the power supply modules share the current conversion capacitor, so that the volumes of the power supply modules are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a multi-stage inductive energy storage pulse power supply and a power supply method. Background technique [0002] The launch of the rail gun requires a pulse current with large amplitude and long duration, which generally requires multiple power modules to jointly discharge the load; and the power module contains high-voltage, large-capacity, and large-volume capacitors. The increase in the number makes the railgun power supply larger, which is not conducive to the actual combat application of the railgun. Contents of the invention [0003] In view of the above analysis, the present invention aims to provide a multi-stage inductive energy storage type pulse power supply and power supply method, which provides pulse current with large amplitude and long duration, and solves the problem that the power supply is bulky and unfavorable for practical application. [0004] Th...
