The pulsed power technology is growing as one of important basic technologies, which are related to free electron lasers, x-ray lasers, x-ray microscope, nuclear fusion, high power microwave and so on. The aim of this research is to develop the 150kJ pulsed power generator, which is compact, light-weight and economical. The obtained results are summarized as follows ;(1) The experiments were carried out to generate a extremely high voltage. The Marx bank with the total capacitance of 25nF and the output voltage of 400kV is connected with a coil of 3.3mH and a copper wire of 60 cm in length and 0.03 mm in diameter. The voltage calculated from the obtained current waveform reached 20MV.(2) The 150kJ capacitor bank was fabricated. Its bank was charged within 20 second by the electric power source of 8kJ/s.(3) The risetime of several ten's ns was achieved by the plasma opening switch using a laser-produced plasma.(4) Though the plasma flow switch can control the conduction time, the matching with load was difficult.(5) Both the conduction and opening times were able to controlled by a combination of copper fuse and plasma opening switch as two-staged opening switch.

脉冲功率技术作为自由电子激光器、x射线激光器、x射线显微镜、核聚变、大功率微波等领域的重要基础技术之一，正在蓬勃发展。本课题的研究目标是研制体积小、重量轻、经济实用的150kJ脉冲发电机。所得结果总结如下：这些实验是为了产生极高的电压而进行的。总电容25nF，输出电压400kV的马克思银行用3.3mH的线圈和长60cm，直径0.03 mm的铜线连接。由得到的电流波形计算出的电压达到20MV。(2)制备了150kJ的电容器组。它的银行在20秒内由8kJ/s的电源充电。(3)利用激光产生的等离子体，实现了等离子体开启开关的上升时间几十ns。(4)等离子体流量开关虽然可以控制导通时间，但与负载匹配困难。(5)铜熔断器与等离子体开断开关组合作为两级开断开关，可以控制导通和开断时间。
