摘　　要：本文介绍了共模扼流圈在直线感应加速器恒流源反向冲击电压抑制中的应用、设计原则、结构形式及其特点,采用纳米晶磁芯研制了大功率恒流源的共模扼流圈。通过理论分析、计算和实验比较,纳米晶磁芯设计的共模扼流圈体积小、结构简单、阻抗稳定性高,对恒流源主要技术指标有明显改善。The design formulae,structure characteristics and application of the common-mode choke were report in this paper.The choke was utilized in suppress of the reverse pulsed voltage of the constant-current source of linear induction accelerator.The common-mode choke was made of nanocrystal magnetic core.Based on systemic analysis,calculation and test,the choke got some advantages compared with the traditional design,such as smaller volume,simpler structure and higher impendenee.The application of the nano-crystal magnetic core improved the main performance character of the constant-current.
