Research on the High Power Magnetic Field Immunity Test System for ITER

Abstract

[Introduction] To ensure the safe and stable operation of the equipment, the power electronic equipment regulated by the International Thermonuclear Experimental Reactor (ITER) organization must pass the relevant magnetic field immunity test. [Method] Based on ITER requirements, the parameter requirements of the required test system were defined. Square solenoid coil and square three coil were selected as the research objects. The structural parameters of the optimal performance were calculated by numerical calculation method, and the correctness of the calculation was verified by finite element method. [Result] Compared with the two coil types, the solenoid with low power consumption is selected as the final structure. Then, based on this parameter, the power topology of DC transient is analyzed, the relevant parameters are calculated, and the performance data required by the final power supply is determined. [Conclusion] The research of this paper provides a detailed calculation process and design reference for the design of induction coil and its power supply of ITER high-power magnetic field immunity test system.
