The NanChang Spherical Tokamak (NCST), a new compact (plasma major radius R = 0.40 m, minor radius a = 0.24 m, and aspect ratio A = 1.67) spherical tokamak, is suitable for teaching and scientific research activities at the university. The principal goal of the device is to initiate plasma currents by utilizing merging compression. At present, the NCST has a total of five complete coil systems, including the coils and their dedicated power supplies, to generate and control the plasma as per the experimental objectives. This paper presents the NCST device and its coils, the design of the power supplies, and the simulation results of plasma configurations as well as the comparison of experimental and simulation results of the above-mentioned power supply system.
