Especially in AC mode, during the booster ramping process, the current ramping profiles of the Quadruple Magnets have to track that of the Dipole AC power supply with precise phase and amplitude to maximize the beam energy boost efficiency. At present, analog current commands for all the booster power supplies with relative phase and amplitude information are generated externally. The current ramping profiles are pre-calculated and calibrated in a centralized manner. In this paper, an auto-calibration process using Curve-Fitting algorithm is proposed. In the new process, the current ramping profile data is first stored digitally in each power supply and then outputted to each power supply with a synchronous trigger signal in hope to eliminate the signal integrality problem inherent in analog signals , so that the beam energy boost up could be more reliable and efficient. The new proposed method has been implemented and tested successfully and will be applied to the booster power supplies to test its performance in the future.
