Conception design of a long-pulsed driver based on FLTD and RLC snubber

Fast linear transformer driver (FLTD) is a novel high current pulsed power source that can obtain a high current pulse of the width of 100 ns directly. The conception design of a long-pulse driver based on FLTD and RLC snubber net in parallel is presented. The primary structure and main electrical parameters and the equivalent circuit are given. The influence of the FLTD electrical parameters and the load electrical parameters on the output waveform are simulated by the Pspice program. The simulated results indicate that the driver has the output voltage of 700 kV and the flat pulsed width of 150 ns at 90% of the magnitude, and the rise time of 20 ns on 100 Ω resistive load.
