Design of Digital Regulating Loop Based on Field Programmable Gate Array

Based on the closeloop control principle of the power supply, the digital regulating loop (DRL) was designed and implemented in the field programmable gate array (FPGA) embeding digital signal processing module. A fully digital controlled power supply was realized based on the DRL. It is proved that the DRL meets the requirements for controlling and regulating a power supply for most accelerator current stabilized magnet power supply system.
