In order to generate a current pulse with tens of milliseconds flattop time on an inductive load for pulse magnetic window technology research, a prototype of pulsed power supply is fabricated and tested. It is composed of several pulse forming units with capacitor banks and a thyristor switch and can generate a flattop current pulse by triggering sequentially the thyristor valve of pulse forming units at certain time or adjust a current waveform by altering triggering time of units. The results show that the prototype with four pulse forming units can generate a current pulse with 5 ms flattop time and 35 kA peak current, and its energy transfer efficiency is significantly higher than that of conventional circuits such as parallel capacitor banks or pulse forming networks.
为了在脉冲磁窗技术研究中在感性负载上产生平顶时间为数十毫秒的电流脉冲，制作并测试了一台脉冲电源样机。它由几个带有电容器组的脉冲形成单元和一个晶闸管开关组成，通过在特定时间依次触发脉冲形成单元的晶闸管阀可产生平顶电流脉冲，或者通过改变单元的触发时间来调整电流波形。结果表明，具有四个脉冲形成单元的样机能够产生平顶时间为5 ms、峰值电流为35 kA的电流脉冲，并且其能量传输效率显著高于诸如并联电容器组或脉冲形成网络等传统电路。
