分布式全固态波形可调高压脉冲发生器研制OA北大核心CSTPCD

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.
