Abstract：
The SSRF (Shanghai Synchrotron Radiation Facility) home-made digital power supply controller adopts advanced DSP and FPGA as core and precision ADC as data acquisition unit. The controller which is inlaid in the power supply case is composed of two cards of ADC and DSP. The controller can communicate with IOC by optical fiber through the UART port. The controller can easily change the parameter of the power supply to achieve high stability and repetition. As a
replacement of the imported PSI controller, the controller is mainly used in the SSRF media power supply (stability less than 100ppm), and can match all of the specifications.
