摘　　要：以兰州重离子加速器冷却储存环(Main Cooler Storage Ring at Heavy Ion Research Facility in Lanzhou,HIRFL-CSRm)四极铁电源为例,介绍了一种大功率数字脉冲电源的模块化设计方法。采用了模块化标准化设计原则,大幅度降低了电源尺寸,提高了原部件集成度和功率密度,对电源进行了热分析。搭建完成了一台样机,通过样机验证,测试了电源热分布及电磁兼容性EMC(Electro Magnetic Compatibility)性能。测试结果表明,这种模块化结构达到了设计要求。Background： The Main Cooler Storage Ring at Heavy Ion Research Facility in Lanzhou （HIRFL-CSRm） has 30 power supplies for the quadrupole magnets, with a big volume of 1 000 mm×1 000 mm×2 000 mm. Purpose： We attempt to significantly reduce the size of the equipment and improve the integration of the components and power density of the power supply. Methods： Firstly, a suitable and original topology is selected for overall design. Through changing the construction of the parts of the rectifier filter, power converter, high-frequency filter and the controller, digitalization, modularization and standardization were applied to reduce the costs and the geometric dimension. Thermal simulation of the power unit was performed before the prototype is completed, and the Electro Magnetic Compatibility （EMC） was tested finally. Results： The size of new designed power supply was decreased to 600 mm×800 mm× 1 800 mm, and the performance testing results satisfied all of the design requirements. Conclusion： The modularized design of high power pulsed power supply not only reduce the geometric volume, increasing its power density, but also improve its overall performance, proving a feasible and meaningful reference for high power density equipment.
