英文摘要	When the power supply of superconducting magnet for Comprehensive Research Facility for Fusion Technology (CRAFT) is operating under short circuit condition and overload, the commutation overlap angle changes dynamically, which greatly increases the complexity in the system modeling and the difficulty in control. To solve these problems, by replacing the circular arc with small bowstring, the dynamic mathematical model under short-circuit operation can be simplified. In order to precisely adjust the impact speed and amplitude of impulse current under short circuit operation, an open-loop control strategy is proposed based on dynamic mathematical model, which can get the excellent performances, inherent stability, fast response and no overshoot. The instantaneous current sharing control strategy using virtual impedance is designed to solve the problem of serious overload and dynamic current sharing under short circuit operation, which thereby ensures the overall overload capacity of superconducting magnet power supply. At last, simulations and experiments are conducted, and results validate the feasibility of the proposed methods.
