Simulation and primary experimentation of fast linear transformer driver module

Modular linear transformer driver (LTD) is a novel fast discharge high power pulsed source on primary storage energy. Modular LTD is a novel fast discharge high pulsed power source on primary storage energy. It can realize many LTD modules in series or parallel connection conveniently, and can directly acquire 100-200 ns high power pulse to load. In order to follow fast LTD technology in the international, further broadened out its application domain, this article introduced the principle of fast LTD technology and the latest development in abroad. According to domestic pulse capacitor, high frequency ferromagnetic and insulator technical level, this paper designed a module of fast LTD with the current rise time 100 ns, the current peak value of 100 kA. A equivalent circuit simulation model is set up and the outer parameters of LTD are calculated with universal circuit simulation software program. The experiment result of a brick is that acquired rise time is about 86 ns, short-circuit current is about 7 kA, inductance of a brick is about 270 nH in charge voltage about ±35 kV. The experiment result indicates that the designed LTD technology project can achieve the desired results.
