300kA直线型变压器驱动源模块实验研究
Experimental investigation of 300 kA fast linear transformer driver stage
摘要
Abstract
Modular linear transformer driver (LTD) is a novel fast discharge high pulsed power source based on primary storage energy. It can realize the connection of multiple LTD modules in series or parallel conveniently, and can directly acquire 100 to 200 ns high power pulses. This paper introduces an LTD stage with the rise time of 100 ns and the current of 300 kA. The stage of LTD consists of 14 bricks in parallel. The 200 kV multi-gap multi-channel gas spark switch with the diameter of 98 mm and the height of 127 mm has been developed. The influence on the load output current of the switch working voltage ratio was investigated. The result indicates that the 14 bricks can discharge synchronously, when the switch working voltage ratio is 0. 7. When the charging voltage of the stage is ±90 kV and the switch gas pressure is 0. 32 Mpa, the output current is about 302 kA, the risetime is about 100 ns (10% to 90%), and the power is about 23 GW on a matched load.关键词
