摘要：

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.
