摘要

In 2016,the power supply in CSRm was digitalized to further improve the reliability of operation.A new vector rectication technique is developed for the research of advanced power supply and electrical related technologies.A number of EMC and electrical safety testing items for HIMM Wuwei power supplies has been completed.Digitalization upgrade of the power supply CSRm power supply,including 30 sets quadrupole magnet power supply,6 sets sextupole magnet power supply and 8 sets bipolar correct magnet power supply,were transformed by using of digital controllers based on FPGA.Fig.1 displays the measurement results of the new digital power supply of quadrupole magnet,the current error(at top)was 1.7610?5,the tracking er-ror was 5.2810?5.The performance and reliability of the power supply have been greatly improved.
