内置触发方式下单级FLTD触发脉冲参数及影响因素

To study the waveform parameters of the trigger pulse of fast linear transformer driver (FLTD) in the internal triggering brick mode and its influence factors for its practical application and structural optimization, a simulation software of the finite integration technique is used to establish a single-stage FLTD field simulation model and to obtain parameters and influence factors of the trigger pulse. And the parameters are validated on the 1 MA FLTD experimental platform. The simulation results show that the leading edge of the trigger pulse increases from 49. 3 ns to 60. 1 ns when the inductance of the trigger brick increases from 100 nH to 350 nH. When the grounding resistance of the trigger brick is less than 200 Ω, the trigger voltage increases with the value of the resistance. When the value of the grounding resistance is greater than 200 Ω, increasing the value of the resistance has little effect on the trigger voltage. Changing the impedance of the azimuthal transmission line in a range from 58.0 to 76.5 Ω has little influence on waveform parameters of the trigger pulse.
