中文摘要： 为了满足国防和工业领域的应用要求，必须对高功率脉冲驱动源固态化、长寿命以及重复频率运行进行研究。本项目提出了一种基于可饱和脉冲变压器的LC-Marx发生器，该发生器由初级储能系统、重频控制模块、可饱和脉冲变压器、主储能电容等组成，输出电压为300kV，重复运行频率为50-100Hz。项目的主要研究内容包括：1）环形磁开关角向饱和特性研究；2）多次级可饱和脉冲变压器多路同步输出特性研究；3）基于可饱和脉冲变压器的LC-Marx发生器理论分析、结构设计以及重频运行实验研究。本项目的特色：采用可饱和脉冲变压器作为LC-Marx发生器主电容器的充电装置，同时通过变压器磁芯由非饱和态到饱和态的转换，其次级发挥磁开关功能，以替代传统Marx发生器中的气体开关；与传统LC-Marx发生器相比，无需外部同步触发系统；通过合理的电路结构设计，磁芯可自动复位，实现Marx发生器的长寿命固态化和重复频率运行。

英文摘要： Solid state, long life time and repetitive operation are very important of high power pulse driver for its widely applicaions in the fields of national defense and industry. A kind of LC-Marx generator based on saturable pulse transformer (SPT) is proposed in this project. This genrator is consisted of primary energy storagy system, controlling system of repetitive operation, saturable pulse transformer, main energy storagy capacitors, et al. The output volage of the generator is 300kV, and the repetitive frequnency is 50-100Hz. The project contains three main contents as follows. 1) angular staration characteristics studies of ring-shaped magnetic switch; 2) accurate synchronization controlling of multi-secondary windings saturable pulse transformer; 3) structure design, experimental studies and repetitive operation researches of saturable pulse transformer based LC-Marx generator. The features of LC-Marx generator proposed in the project are as follows. SPT is employed in this generator to work as the charging system of main capacitors. At the same time, the secondary windings of SPT play as a magnetic switch with the magnetic core transformation from unsaturaed mode to saturated mode. The gas gap switch in the traditional Marx generator is replaced. No outside reset system is necessary compared with the traditional LC-Marx generator. Automatic reset of magnetic can be relized with resonable electric circuit design. And the long life time, solid state and repetitive operation of the generator are relized.
