摘要	In order to improve the breakdown stability of gas switch in CO2 laser, to improve the efficiency of trigger system, and to reduce the loss of trigger system, we developed a set of high-voltage pulse trigger generator (microsecond level) based on two-transistor forward topology. In the generator, high voltage pulses (the number is adjustable) with am-plitude exceeding 38 kV and width of 10 s was adopted to breakdown hyperbaric gas between electrodes of spark switch, dry-type high-voltage transformer was used as a booster unit, and the sampling and feedback control circuit that mainly con-sists of SG3525 and CD4098 was designed to monitor the situation of spark switch and control the frequency and number of output pulses. The experimental results show that breakdown probability of this pulse trigger generator is 99.7%, the ef-ficiency is 0.2, and the loss is 0.88 kW, when the PRF is 500 Hz. Compared to traditional trigger system, the breakdown probability of our design is increased by 2.7%, the efficiency is increased by 0.12, and the loss is reduced by 1.512 kW. 2018, High Voltage Engineering Editorial Department of CEPRI.
