HIAF (High Intensity heavy ion Accelerator Facility) is a project proposed by IMP (Institute of Modern Physics, Chinese Academy of Sciences). This paper designs a digital controller for Bring in HIAF dipole power supplies system, which is several circuit boards consist of high precision ADC, optical fiber module, DDR3 SDRAM, Gigabit Ethernet module. It uses Cyclone V SX SoC FPGA, which integrated with dual-core ARM Cortex-A9 MP Core processor. This paper explains the hardware and software architecture of the controller and how can it improve power supplies performances. The FPGA finishes the PI regulating and PWM modulation. The ARM is responsible for data pre-setting, web service, database, and power supplies detection and protection management. At the end, this paper gives the output measurements when the controller is used in the prototype, which verifies the rationality and reliability of the design.
