Design of an Active Ripple Compensator for the 50-T High-Stability Flat-Top Pulsed Magnetic Field.

High-stability flat-top pulsed magnetic field can meet severe demands of field intensity and stability in modern scientific experiments. The higher stability of the flat-top magnetic field would be of more benefit to the observation of experimental phenomena (such as specific heat measurement andNMRexperiment). In order to reduce the ripple of the flat-top magnetic field, an active ripple compensator is presented in this paper for the 50-T dual-coil magnet system at the Wuhan National High Magnetic Field Center. The active ripple compensator has the advantages of modularization, flexibility, and low energy consumption. The simulation model including the generator-rectifier power supply is established on the MATLAB/Simulink platform. The ripple of a 50-T magnetic field has been reduced from 1500 to 60 ppm, which verifies the feasibility of the scheme. [ABSTRACT FROM AUTHOR]
