马克思发生器是一种用于功率脉冲压缩的升压装置，其电容器并联充电，串联放电。为了获得更高的升压比，高压硅堆已被应用于替代隔离电感在这项研究中。在马克思发生器中进行了两种隔离模式的实验。实验结果表明，马克思发电机采用50 kV/3 kA高压硅堆，可使升压比由采用隔离电感时的141：1和采用50 kV/3 kA高压硅堆时的162.9：1提高到168.6：1。此外，硅堆隔离型马克思发生器在采用隔离电感的情况下，几乎可以消除负载上存在的预脉冲。因此，选择合适的高压硅堆作为本研究设计的马克思发生器的隔离器件至关重要。
Marx generator is a voltage boosting device for power pulse compression, in which its capacitors are charged in parallel and discharged in series. To get a higher voltage boost ratio, high-voltage silicon stacks have been applied to substitute the isolated inductances in this study. Experiments with two isolation modes in the Marx generator have been carried out. Experimental results reveal that the high-voltage silicon stacks with the parameters of 50 kV/1 kA used in the Marx generator can increase the voltage step-up ratio to 168.6:1, up from 141:1 and 162.9:1 when isolating inductances and silicon-stacks with parameters of 50 kV/3 kA are applied, respectively. Moreover, the silicon stack-isolating-type Marx generator can almost eliminate the pre-pulse existing on the load if the isolated inductances employed. Therefore, it is crucial to choose appropriate high-voltage silicon stacks as the isolating devices in the Marx generator designed in this study.
