摘要
我们描述了一种新型模块化级联 H 桥大功率加速器偶极磁体脉冲电源，用于兰州重离子研究装置-冷却器-存储环主环（HIRFL-CSRm）。该电源由两个并联的分支组成，每个分支由四个串联的 360 V/1800-A 功率单元组成。每个电源单元的交流/直流转换器使用并联的模块化高功率密度电压源，直流/交流转换器使用级联 H 桥。此外，还采用了数字控制策略。电压源模块采用电压和电流双闭环控制，级联 H 型电桥采用电流双闭环控制、倍频调制和级联多电平控制。通过实验证实了所提出的拓扑方案和控制策略的有效性，并通过 72 小时连续输出实验验证了电源的热稳定性。
A Novel Modular Cascaded H-Bridge High-Power Accelerator Dipole Magnet Pulse Power Supply for HIRFL-CSRm
We describe a new modular cascaded H-bridge high power accelerator dipole magnet pulse power supply for the Heavy Ion Research Facility in Lanzhou-Cooler-Storage-Ring main ring (HIRFL-CSRm). The power supply consists of two branches connected in parallel, each of which consists of four 360 V/1800-A power units connected in series. Each power unit uses modular high power density voltage sources in parallel for the ac/dc converter and cascaded H-bridges for the dc/dc converter. In addition, digital control strategies are implemented. The voltage source modules adopt voltage and current dual closed-loop control, and the cascaded H-bridges use current dual closed-loop control with frequency-doubling modulation and cascaded multilevel control. The effectiveness of the proposed topology scheme and control strategies is confirmed through experiments, and the thermal stability of the power supply is verified through 72-h continuous output experiments.
期刊介绍：
The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years.
The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
