摘　　要：介绍了目前国际高能粒子加速器领域中大功率固态高压脉冲调制器的发展状况,讨论了串联开关型和感应叠加型两种技术路线的特点,后者因输入电压低、变压器采用同轴结构等原因有一定的优越性。建立了单元电路的简化模型,仿真显示减少单元电路漏感是实现快速脉冲的关键。该路线涉及大功率IGBT快速驱动技术、同轴磁芯设计等其它关键技术。最后给出了一台34 MW速调管的调制器设计方案和单元电路输出波形。The present status of the development of high power, high voltage solid-state modulators in the field of accelerators is presented. Two circuit topologies, series switches and induction adder, are described and discussed. An emphasis of discussion is put on the induction method. Because of the low input voltage and coaxial transformer structure, the method has advantage over other choice. A simplified cell circuit simulation model is established. The simulation indicates that reducing the leakage inductance is the way to get fast rise time. Other important components include fast driver of high power IGBT switch, coaxial transformer design, etc. Finally, the design of a prototype 34 MW, solid-state modulator is presented and waveforms of the cell circuit are presented.
