Abstract
The power supply scheme for the superconducting outsert of Steady High Magnetic Field Facility (SHMFF) in High Magnetic Field Laboratory of Chinese Academy of Sciences is a switching power supply with active DC power filter. In this paper, a novel shunt liner active power filter (SLAPF) is designed to overcome the disadvantages of existing dc active filter schemes. The system structure and working principle are presented at first. Then the design flow is described, which includes the control method of the current compensator, the analysis of topology chosen for auxiliary power supply, At last, the experimental results show that the filtering effect of SLAPF is good enough to make the power supply meet the technical requirements.
