提出了一种基于脉冲变压器的紧凑型双极脉冲形成网络(PFN)-马克思发生器。高压发电机由两组脉冲变压器、6级带陶瓷电容器的pfn、一个开关单元和一个匹配负载组成。该设计的特点是双极脉冲充电方案和PFN-Marx的紧凑结构。脉冲变压器双极充电方案提高了pfn中陶瓷电容器的耐压，减少了气隙开关的数量。PFN-Marx的紧凑结构旨在减少发电机中的寄生电感。当pfn上的充电电压为35 kV时，匹配的48 Ω电阻性负载可输出幅值为100 kV的高压脉冲。负载脉冲的半峰值全宽为173 ns，上升时间小于15 ns。
A compact bipolar pulse-forming network (PFN)-Marx generator based on pulse transformers is presented in this paper. The high-voltage generator consisted of two sets of pulse transformers, 6 stages of PFNs with ceramic capacitors, a switch unit, and a matched load. The design is characterized by the bipolar pulse charging scheme and the compact structure of the PFN-Marx. The scheme of bipolar charging by pulse transformers increased the withstand voltage of the ceramic capacitors in the PFNs and decreased the number of the gas gap switches. The compact structure of the PFN-Marx was aimed at reducing the parasitic inductance in the generator. When the charging voltage on the PFNs was 35 kV, the matched resistive load of 48 Ω could deliver a high-voltage pulse with an amplitude of 100 kV. The full width at half maximum of the load pulse was 173 ns, and its rise time was less than 15 ns.
