摘　　要：通过对多个脉冲功率发生器的输出进行同步叠加可以获得功率合成。脉冲叠加还可以使脉冲功率源的设计和制作走向模块化。从直线变压器驱动源(LTD)的观点出发,综合论述了脉冲叠加在重复频率脉冲功率技术中的意义。特别针对固态LTD,通过实验结果归纳了它的技术特征,并在此基础上提出了智能化脉冲功率的概念。The pulse adding has been used in super-large pulsed power machines in order to achieve extremely high output power by overcoming the physical limitations of a single pulsed power generator. The inductive voltage adding is an effective way to improve the system flexibility, compactness, and easiness of maintenance. The linear transformer driver （LTD） is a relatively new technology of pulsed power generation based on the concept of pulse adding. In addition, solid-state LTD has further extend- ed this technology to ＂smart pulsed power＂ by introducing the functions of arbitrary waveform synthesis and logical response to the load behavior.
