Research and Design of Digital Power Supply for HIRFL-CSR Sextupole Magnet

    Graphical Abstract
    • Abstract
  • One digital power supply was designed for the sextupole magnets of CoolerStorageRing of the Heavy Ion Research Facility in Lanzhou (HIRFLCSR). It adopts HBridge convertor as the main topology circuit and Cyclone II FPGA as the main hardware, and has realized fully digitized PI regulation arithmetic by Verilog language. The peak current of the power supply reaches 340 A and the stability approaches 3.14×10-5. Finally the power supply has achieved the designed specification of 1×10-4.
