Abstract: One digital power supply was designed for the sextupole magnets of CoolerStorageRing of the Heavy Ion Research Facility in Lanzhou (HIRFLCSR). It adopts HBridge 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.
