摘　　要：在实验室开展地面物体雷电上行先导特性研究,亟需研制用于电场时变特征等效模拟的新型冲击电压发生装置。该文聚焦于装置研究的关键技术问题,从装置技术要求出发,提出以电容可控充电单元电路为核心的多级串联式装置电路拓扑,分析了单元电路特性及拓扑应用中的主要技术问题。并以1.3 MV电压发生装置为典型实例,提出了装置的具体参数配置方案,通过装置性能分析验证了装置设计的合理性。进而提出实现多级串联的装置具体结构,并通过研制样机开展性能试验验证了该结构的可行性,解决了多级串联式装置电路拓扑的物理实现问题,为最终实现雷电上行先导模拟试验用新型冲击电压发生装置提供理论指导和实践依据。For the characteristics research of upward lightning leader in the laboratory, new type of impulse voltage generator is urgently needed for the equivalent simulation of electric field in temporal characteristics. Focusing on the key technical problem of generator＇s development, the topology of generator was presented in the first, which was based on the technical requirements for the generator and had the feature of multi-stage circuits connected in series with the cell circuit of controllable capacitor charging as core, and the characteristics of cell circuit as well as major application problems of the topology were analyzed. Then taking 1.3 MV generator as a typical example, scheme of concrete parameter configuration was provided, rationality of which was verified on the basis of performance analysis. Furthermore the layout design of generator was proposed to realize multi-stage circuits connected in series physically, feasibility of which was testified by means of developing prototype generator as well as performance experiment, and the realization problem of generator was solved in this way. This paper will provide theoretical guidance and practical basis to the realization of new impulse voltage generator for the simulation experiment of upward lightning leader in the final.
