Described in detail based on the FPGA program digital power regulator. First introduced the hardware design of the digital regulator module design, focusing on the working principle of the high-speed high-precision AD7634 for sampling the power supply output current is described, and gives the AD7634 to collect a voltage signal waveform; followed by the introduction of digital adjustment The software design of the device, including the regulator algorithm, the function and the implementation method in the FPGA is introduced. Finally, a 15 A / 15 V calibration magnet power supply is used as a prototype to conduct the closed-loop regulation experiment and the test results are given.
