紧凑型电感隔离快Marx发生器

为了实现脉冲功率装置小型化和实用化,作为初级储能装置的Marx发生器,采用紧凑型结构设计的直接驱动装置成为研究热点。为探索紧凑型Marx直接驱动负载的可行性及相关的设计方法,设计了一台采用电感作为充电和接地器件的紧凑型气体绝缘快前沿Marx发生器并进行了相关实验。初步的实验结果表明,Marx放电正常,充电19kV时,在26Ω负载上可得到145kV的高压脉冲输出。可看出Marx发生器直接驱动有其自身的优势,需要注意的是发生器与负载的连接问题。

Compact Inductively Isolated Fast Marx Generator

This paper describes work on the design and tested of an inductor isolated compact fast Marx generator.This generator is made of 10 stages and each stage has 6 paralleled high voltage ceramic capacitors potentially charged to 30kV per capacitor.An annular field aberrance switch whose triggered electrode is in the center has been designed to achieve the generator's erecting.The self-breakdown switches have a similar structure.The difference is a structure which can increase the capacitor between the electrode of the self-breakdown switch and the ground has been designed to minish the erect time.Unique features of the Compact Marx is all the switches have a common switch housing run through the center of the whole Marx.The advantage is the ultraviolet radiation that is generated by the switch can help the next switch's breakdown and the structure is simple and compact.We use gas as the insulation medium of the Marx system.All parts of the set are airproofed in a common gas house.So the charge voltage and the output voltage can be adjusted by the air pressure and kinds of insulation gas.The primary test prove that the design can achieve the objective basically.It can get 145 kV minus pulse singnal on the 26 omiga load when the capacitors are charged 19 kV and the erect inductor is only 170 nH.
