THE SSRF STORAGE RING DIPOLE AND SEXTUPOLE MAGNET POWER SUPPLIES

摘要

SSRF is a third generation synchrotron radiation light source. It has a full energy injection storage ring of 3.5GeV.[1] The storage ring dipole magnet string and sextupole magnets strings are powered by 10 large magnet power supplies. The power supply output current ranges from 250A to 800A, and the output voltage ranges from 140V to 840V. These power supplies are digitally controlled, with bridge topology, and diode rectifiers with step-down transformers. In this paper, the commissioning results and the operation experience of these power supplies are presented, together with the circuit topology and the control schemes.
