摘　　要：为了满足多领域对幅值、脉宽、波形、重复频率等参数的不同要求,基于分布式理念,提出了一种分布式全固态波形可调高压脉冲发生器。该脉冲发生器由多个结构相同的子模块构成,单个模块采用半桥结构的全固态Marx主拓扑,驱动采用磁隔离方案;每个模块具有统一设计的连接端子与通信协议,多个模块可以独立工作,也可以直接串联工作以获得更好的性能。整个装置采用分层式设计,结构紧凑。详细阐述了该发生器的电路拓扑、工作原理与波形产生方法,并搭建了3台8级基本单元的9电平试验样机,串联后可输出25级电平的单极性任意高压脉冲波形,最大输出电压达到16 kV。To meet the different requirements of different fields for parameters such as amplitude,pulse width,waveform,and repetition rate,a distributed all-solid-state waveform adjustable high-voltage pulse generator has been developed based on the distributed concept.This pulse generator comprises multiple sub-modules with identical structures.Each module is based on the all-solid-state Marx with the half-bridge structure,while the drive uses a magnetic isolation scheme.Moreover,every module has a uniformly designed connection terminal and communication protocol.Multiple modules can operate independently or directly in series to achieve superior performance.The entire device features a layered design and compact structure.This paper elaborates on the pulse generator's circuit topology,working principle,and waveform generation method.Finally,three 9-level test prototypes with 8-level basic units have been constructed,which can produce a 25-level unipolar arbitrary high-voltage waveform in series.The output peak voltage can reach 16 kV.
