  One digital power supply was designed for RIBLL (Radioactive Ion Beam Line in Lanzhou) corrector magnet at HIRFL (Heavy Ion Research Facility in Lanzhou). Adopting two parallel connected IGBT full-bridges as the power circuit topology, the power supply can generate bipolar DC current when it runs in the fourquadrant working states, which well meets the requirements of corrector magnet. SOPC platform of Altera based on Nios II is chosen to design the digital power supply regulator. Employing FPGA as the control core and utilizing SOPC principles, the digital regulator is designed against special requirements of accelerator power supply. The test results indicate that performance of the power supply can meet the design requirements.

  This paper introduces a kind of pulsed power supply at HIRFL-CSR,analyzes the ripple and current error of the quadrupole magnet power supply in the operation process, and gives a two-stage topology of pulsed power supply. The control method is simulinked and the results show that the new one can make up for the deficiencies of the existing pulse power supply and the main circuit structure and control method are feasible.
