摘要

介绍了一种基于双极马克思电路的全固态高压脉冲发生器。采用基于磁芯变换的碳化硅mosfet驱动电路传输驱动信号,实现驱动电路对主马克思电路的磁隔离,提高器件工作的一致性。首先对发电机的拓扑结构和工作原理进行了描述,并对发电机的主要部件进行了设计。然后,给出了磁隔离驱动的详细电路,分析了磁隔离驱动的工作原理。实验结果表明,所研制的双极马克思脉冲发生器能够输出振幅为±5kV、上升沿为26ns、下降沿为96ns的极性可调脉冲。

All-solid-state High-voltage Marx Pulse Generator Based on Magnetic Isolated Drive Circuit
An all-solid-state high-voltage pulse generator based on the bipolar Marx circuit is presented in this paper. A drive circuit of the silicon carbide (SiC) MOSFETs based on the magnetic core transforms is used to transmit the drive signals, in order to get the magnetic isolation of the drive circuit to the main Marx circuit and improve the consistency of the devices’ operation. First, the topology and operating principles of the generator are described, and main components of the generator are designed. Then, the detailed circuit of the magnetic isolated drive is presented and operational principles are analyzed. Finally, experiments are carried out and the test results show that the developed bipolar Marx pulse generator can output the polarity adjustable pulse with the amplitude of ±5kV, and rising edge of 26ns and falling edge of 96ns.
