Experimental study on FLTD stage and its discharge synchronization

This paper summarizes the design and test results of twelve-brick fast linear transformer driver(FLTD) stage. The configuration and critical components of the stage are introduced. The self-breakdown voltage and triggering feature testing of all the switches is operated. When the charge voltage of the stage is 150 kV, the short-circuit output current is 235 kA, and the current rise time is 88.2 ns(10% to 90%). For a 0.58 load, the output current is 114.5 kA, and the current rise time is 88.9 ns(10% to 90%). Discharge synchronization of all the twelve switches with charge voltage of 120 kV is studied with differential loop. The experimental results indicate that the probability curve for discharge synchronization is consistent with the Gaussian curve approximately for 100
