Abstract

The repetitive pulsed power generators were constructed with the semiconductor opening switches (SOS) realizing the pulse compression by inductive energy storage scheme. For the preliminary pulse compression, the magnetic pulse compression system was employed. The saturable inductors and transformers transferred the stored electrical energy from the primary storage capacitor to the SOS compressing the pulse. For the final stage of the generator, the SOS was used. By tuning the current fed to the SOS, the amplitude and pulse duration of the generated voltage at the 300-/spl Omega/ resistive load were 150 kV and 60 ns, respectively. Also, general-purpose fast-recovery diodes (FRD) were tested from the viewpoint of the potential candidate as the SOS. The properties of two diodes, of which the reverse recovery time is 100 ns, were tested and found to be enough good as an opening switch. Combining WC and SOS pulse compression scheme, pulsed voltage of 50 kV in amplitude and 20 ns in FWHM is obtained from the relatively low charging voltage of 1.4 kV, which can be repetitively ignited by a semiconductor closing switch.

基于半导体开路开关的重复脉冲功率发生器

采用半导体开路开关(SOS)构成重复脉冲电源，实现电感式储能脉冲压缩。初步脉冲压缩采用磁脉冲压缩系统。可饱和电感器和变压器将储存的电能从初级储存电容器转移到压缩脉冲的SOS。对于发电机的最后阶段，使用了SOS。通过调整供给SOS的电流，在300-/spl ω /阻性负载下产生的电压幅值和脉冲持续时间分别为150 kV和60 ns。此外，通用快速恢复二极管(FRD)从潜在候选SOS的角度进行了测试。测试了两个反向恢复时间为100 ns的二极管的性能，发现它们足够好地用作开闸开关。结合WC和SOS脉冲压缩方案，在1.4 kV相对较低的充电电压下获得振幅为50 kV、频宽为20 ns的脉冲电压，可通过半导体闭合开关重复点燃。
