| Abstract: | In the analysis of current sharing characteristics of toroidal field magnet power converter, the
equivalent circuit model of the high-power converter bridge arm is established by segmenting the bridge arm and
extracting the distribution parameter matrix of branches, and the current sharing coefficients of each branch are
calculated. The bridge arm current of the converter is obtained by simulation. The simulation results are basically
consistent with the analysis, and the current sharing coefficients are all less than the design value of 1.20. |
