最近，已经开发了使用磁脉冲压缩（MPC）和半导体开关的重复脉冲功率发生器。研制了一种重复频率短脉冲臭氧发生器。在这项工作中，短脉冲发生器由一个控制器，一个命令充电器，一个高速晶闸管，MPC和Blumlein线。控制器和命令充电器能够控制到MPC的充电电压和脉冲重复率。高速晶闸管，这是改善了开关速度的脉冲功率应用，产生的主要脉冲。MPC具有使用脉冲Transformer和饱和Transformer的单级脉冲压缩电路。饱和Transformer具有两种功能，升压Transformer和磁开关。Blumlein线是短脉冲发生器的最后一级。Blumlein线为三同轴几何结构，其外电极直径为110 mm，中间电极直径为20 mm，内电极直径为4 mm，长度为500 mm。输出电压约为65 kV的短脉冲发生器，使用每秒150个脉冲（pps）的脉冲重复率和小于10 ns的脉冲持续时间来产生臭氧。报道了用短脉冲发生器和简单同轴电极产生臭氧的实验结果。得到的臭氧浓度为18 g/m3/sup 3/。
Recently, repetitive pulsed power generators using magnetic pulse compression (MPC) and semiconductor switches have been developed. A repetitive short-pulsed generator for an ozonizer was studied and developed. In this work, the short-pulsed generator consists of a controller, a command charger, a high-speed thyristor, a MPC and a Blumlein line. The controller and the command charger are able to control the charging voltage to the MPC and the pulse repetition rate. The high-speed thyristor, which was improved in switching speed for the pulsed power applications, generated the primary pulse. The MPC has single stage pulse compression circuit using a pulse transformer and a saturable transformer. The saturable transformer has two functions, a step-up transformer and a magnetic switch. The Blumlein line is the final stage of the short-pulsed generator. The Blumlein line is three-coaxial geometry, which has an external electrode diameter of 110 mm, a middle electrode diameter of 20 mm, an internal electrode diameter of 4 mm, and a length of 500 mm. The short-pulsed generator which has an output voltage of about 65 kV, pulse repetition rate of 150 pulses per second (pps) and a pulse duration of less than 10 ns was used to generate ozone. The results of ozone production using the short-pulsed generator and a simple coaxial electrodes are reported. The attained concentration of ozone was 18 g/m/sup 3/.
