1MV/100kA快脉冲直线型变压器驱动源装置设计
Design of the 1 MV/100kA Fast Linear Transformer Driver Generator
摘要
Abstract
Fast linear transformer driver（LTD） is a new pulsed power technology that can directly produce fast pulse with rise time less than 100 ns which could be widely used in Z-pinch,radiography,high power microwave and some other research fields.To master the design techniques of LTD,we designed a 1 MV/100 kA fast LTD generator on the basis of 100 kV/100 kA-LTD stage prototype which had been constructed and tested successfully.The generator consists of 10 LTD stages connected in series,and the stored energy is 20 kJ.The outer diameter of the generator is about 1.5 m,at a length of 2.2 m.According to the equivalent circuit simulation,the generator can deliver 1.08 MV fast pulse in 51 ns with 168 ns FWHM into a 10 Ω load.The magnetically insulated transmission line（MITL） geometries of LTD with tapered and straight center conductors was simulated by PIC code.It is shown that the output voltage and the resistance are 1 MV and 10 Ω for both two geometries,respectively.The electron flow in the gap of coaxial transmission line can be magnetically insulated.关键词
