The digital power supply control module (DPSCM) was designed for accelerator high precision current stabilized magnet power supplies. Based on the topology of the switching mode, the power supply embedding the DPSCM fulfilled all-digital control and regulation. The field programmable gate array (FPGA) was chosen as the control component for the DPSCM. The control of high precision ADC and DAC, the digital regulating loop, and the logic control and interlock protection were implemented in the FPGA. The high precision pulse width modulation (PWM) signals were produced by the DPSCM. After testing on the load simulator and the digital power supply prototype, it is proved that the DPSCM can meet requirements for most accelerator magnet power supplies. The current stability of the prototype is better than 5 × 10~(-5) after 72 h test.
