Stability of the correcter power supply is important for beam orbit stability of a synchrotron light source. In this paper, we report a digital control system for corrector power supply of the HLS storage ring, including the hardware, software and the measurement results. The hardware structure and work flow of the digital power supply controller is emphasized. The controller is composed of two cards of ADO and DSP. It adopts advanced DSP and FPGA as core. The controller communicates with IOC via optical fiber, and can easily change parameters of the power supply through the UART port. Operation of the storage ring with the digital control system for correcting the power supply indicates that the upgraded PS system meets the requirement of orbit stability.
