英文摘要	During the operation of Tokamak power system, a large number of low frequency harmonic currents with complex spectrum will be generated. Low-frequency resonance suppressor is an effective solution to suppress this low-frequency harmonic currents. The low-frequency harmonic suppression theory of low-frequency resonance suppressor is analyzed in this paper. Meanwhile, the state space equation of three-phase four-wire neutral-point-clamped rectifier is established in the LFRS. According to the mathematical model, the double closed-loop and zero sequence current control strategies are proposed to improve power factor operation on AC side and neutral point potential balance control on DC side of three-phase four-wire converter. The results show the correctness of the theoretical analysis and provide a technical reference for suppression of low-frequency harmonics of other Tokamak devices. (C) 2021 Published by Elsevier Ltd.
