High power pulse power as the main part of the electromagic launch technology, is being more and more get the attention of people. In order to meet the needs of space electromagic launch technology, high precision pulse power system is very important, and the design of the main circuit topology of pulse power supply is an important research question. This paper mainly introduced the electromagic emission experiments of pulse power system of main circuit topology structure, properties, and using saber circuit simulation software simulation was carried out on the main circuit theory. The main works are as follows: 1. Established the mathematical model of pulse power main circuit: Introduces the position of millisecond pulse power supply system and introduces the important ponents and related parameters, and analyzes the various elements play a role in the main circuit, at the same time, indicate the ponents selection basis,through the theory of software simulation, which determine the pulse power supply power ponents of the system parameters. 2. Through the saber in the circuit simulation software simulation of pulse power supply circuit topology, different line current and voltage in the circuit are obtained with the change of time curve, to identify them in a short period of time (milliseconds or microsecond) change effect, and by, adjusting, finally get the best pulse power main circuit topology structure to conform to the requirements of the electromagic emission of pulse power supply. Key words: electromagic launch, pulse power, topology structure, simulation III 目 錄 摘 要 ...........................................................................................................................I 第一章 緒 論 ......................................................................................................... 1 課題的背景及意義 .......................................................................................... 1 ......................................................... 1 ......................................................................... 2 ............................................................................................... 3 ............................................. 3 ................................................................. 5 ............................................................................................. 10 電磁發(fā)射用脈沖電源的設計課題的研究意義 ............................................ 11 ......................................................................................................... 12 第二章 脈沖電源的原理 .................................................................................. 13 ..................................................................... 13 ......................................................................... 16 ................................................................. 18 ..................................................................................... 19 ......................................................................................................... 19 第三章 脈沖電源的結構 .................................................................................. 20 ................................................................................................................. 20 ......................................................................................... 21 ..................................................................... 22 器件的參數(shù)選擇 ............................................. 24 ....................................................................... 24 R ........................................................................... 24 L ....................................................................................... 25 ............................................................................................... 25 ............................................................................. 26 IV ....................................................................... 26 Marx發(fā)生器開關管 .................................................................... 28 ......................................................................................................... 29 第四章 脈沖電源單個模塊結構的 saber仿真 ......................................... 30 ......................................................... 30 ......................................................... 30 ................................................................................................. 31 ....................................................................................... 31 ....................................................................... 33 ......................................................................................................... 36 第五章 總結和展望 ........................................................................................... 37 參考文獻 ................................................................................................................... 38 致 謝 ........................................................................................................................ 41 南京工業(yè)大學本科生畢業(yè)設計（論文） 1 第一章 緒 論 課題的背景及意義 伴隨著物理技術不斷的進步和發(fā)展，使目前發(fā)射裝置如大炮、火箭等類型的發(fā)射器
