  According to the features of digital power supply and the requirements of pulse mode,this paper introduces a Digital Power Supply Control Mode(DPSCM) in Heavy-Ion Accelerator based on dual Nios cores,which meets the requirements of two basic running modes. The new method develops a system on-chip based on dual Nios cores by using SOPC technology in the Altera EP2C70 FPGA. Compared with traditional DPSCM,the dual Nios cores run simultaneously and cooperate well. As a result,the efficiency of the system is remarkably improved. Further,cores in parallel can realize reference waveforms switch in pulse mode effectively. We choose a 1150A/185V power supply as test bench. The Experimental result indicates that the system can realize the function of pulse mode,and the stability and tracking error meet the design requirements.
