  •   Introduction  The paper aims to effectively suppress the disturbance of non characteristic harmonics to the power grid in the tokamak power supply system, the paper studies the mechanism of low-frequency harmonics in the tokamak power supply system.
      Method  By introducing an improved switching function model, selected ITER fusion device as an example and established its corresponding AC/DC equivalent circuit model combined with its corresponding parameters, the corresponding output second harmonic was obtained through calculation and simulation.
      Result  The ratio of output to input is calculated, and the stability factor value almost tends to zero.
      Conclusion  It is determined that the DC bias of rectifier transformer do not cause harmonic instability of the system.
