摘　　要：针对强流重离子加速器装置(HIAF)离子源束流快速切换需求,设计并研制了一台快切束脉冲电源。根据兼顾电流快速变化和平顶稳定度的要求,提出了基于高低压双前级电压快切换的实现方案,分析了电路工作原理,计算了关键参数,讨论了适应电压突变的控制方法。根据电源模块化原则研制了16kW整机并在真实磁铁负载进行了测试。结果表明,电源在13mH电感上输出570A,误差小于±1×10-4,重复频率3Hz,上升下降时间小于30ms,平顶900ms内可调,电源设计方案合理可行。A fast pulsed power supply is developed to meet the requirements of High Intensity heavy-ion Accelerator Facility(HIAF)ion source.Based on front-stage voltage fast switching method,we proposed a circuit topology ensuring fast rising of current and flat top stability.In this paper the circuit is analyzed,the essential parameters of the circuit are calculated,and the control method is established for adapting abruptly-changed voltage.A 16 kW power supply based on the principle of modular manufacturing was tested on real magnet load.The results show the value of flat top current reaches 570 A,the error is less than±1×10-4,the repetition frequency reaches 3 Hz,the rise time and fall time is less than 30 ms,the flat top time can be set within 900 ms.
