Abstract:
The deviation of the beam orbit can be quickly corrected by the fast corrector power supply, which improves the reliability of the operation of the synchrotron radiation light source. With the further improvement of the quality of the fourth-generation Diffraction-Limited Storage Ring (DLSR) light source, the Fast Orbit FeedBack (FOFB) system places higher requirements on the performance of the corrector power supply to achieve the stability of the beam orbit. In this paper, the current research achievements of beam orbit fast corrector power supply in international fourth-generation synchrotron radiation light sources are divided into two categories: linear power supply and switching power supply. According to the requirements of the FOFB system in the advanced synchrotron radiation light source for the fast corrector power supply, the topology, control strategy and performance parameters of each scheme are briefly compared and analyzed.
