摘要
爆磁压缩发生器常用来驱动脉冲调制器,在二极管上产生高功率短脉冲。进行了两个100 kA动态级联型爆磁压缩发生器延时驱动一台由脉冲变压器和脉冲形成线构成的脉冲调制器的实验。两个爆磁压缩发生器由延时起爆器延时20 ms起爆并用熔断丝进行相互电隔离,在负载二极管上产生了间隔约20 ms、功率大于20 GW的两个脉冲。实验表明:用更多的爆磁压缩发生器驱动单台脉冲功率调制器产生多脉冲的方案是可行的,该方法可用于大功率重频加速器中脉冲功率器件的电恢复性能测试。
The explosively-driven flux compression generators（FCGs） are always used to drive pulse modulators, and high power pulses can be generated on the diodes. In this paper, two dynamically cascaded FCGs were ignited one after another to drive a modulator made up of a pulsed transformer and a pulse forming line（PFL）. The two FCGs were controlled by a selftimer with 20 ms interval and the electrical isolation between them was achieved by two fuses. Two pulses with peak power more than 20 GW and pulse interval 20 ms were generated on the diode. The experiment shows that multiple pulses could be obtained by a single modulator if more driving FCGs are used. This method could test the pulsed power apparatus＂ electricity recovery characteristics, which are necessary to build high power and high repetitious frequency accelerators.
