A trigatron spark gap, T-150, rated at 300 kA for a single shot, has been evaluated for repetition rate applications towards 100 Hz at reduced currents. Switching voltage range was varied from 10 to 40 kV via gap-pressure and gas flow settings. Its trigger generator, producing 8-20 kV pulses, is solid-state based and fiber optically linked for electrical isolation. Trigger energy has been minimized to prolong the overall switch life, drawing input power of <75 W at up to 100 Hz. Demonstrated repetition rate, lifetime, and prefire performance indicated the use of the switch as an alternative to ignitrons or thyratrons in medium power modulators.

To improve the probability and stability of breakdown discharge in a three-electrode spark-gap switch for a high-power transversely excited atmospheric CO2 laser and to improve the efficiency of its trigger system, we developed a high-voltage pulse trigger generator based on a two-transistor forward converter topology and a multiple-narrow-pulse trigger method. Our design uses a narrow high-voltage pulse (10 μs) to break down the hyperbaric gas between electrodes of the spark-gap switch; a dry high-voltage transformer is used as a booster; and a sampling and feedback control circuit (mainly consisting of a SG3525 and a CD4098) is designed to monitor the spark-gap switch and control the frequency and the number of output pulses. Our experimental results show that this pulse trigger generator could output high-voltage pulses (number is adjusted) with an amplitude of >38 kV and a width of 10 μs. Compared to a conventional trigger system, our design had a breakdown probability increased by 2.7%, an input power reduced by 1.5 kW, an efficiency increased by 0.12, and a loss reduced by 1.512 kW.
