摘　　要：The cell circuit design and test of inductive adder pulse generator for kicker magnet are presented in the paper.The 3.3kV IGBT,a large dimension nanocrystalline core and a 2.5kV 50uF energy storage capacitor are used. The multi-channel trigger IGBT driver board is designed.IGBT failures under short circuit condition and protection scheme are explored.The multi-cell prototype is designed.The waveforms of experiments are presented.It turns out that the rise and fall time of the output pulse is fast and the pulse width is adjustable.The maximum current of pulse reaches 2kA.It satisfies the higher requirement of beam injection technology.文章介绍了用于冲击磁铁的感应叠加型脉冲发生器的实验装置.电路中采用3.3kV/800A IGBT开关,大尺寸纳米晶磁环,2.5kV/50uF储能电容.设计了基于CPLD的多路延时可调、光耦输入触发驱动电路.探讨了IGBT短路时的失效原因及保护措施.利用现有的组元电路,进行了多个单元叠加的样机实验,给出了实验波形.结果表明输出脉冲上升下降时间较快,脉宽可调,最大脉冲电流可达2kA,可以满足束流注入技术的进一步提高的要求.
