超导储能脉冲功率系统中，关键的电路元件是断路开关，它的关断性能直接决定了输出脉冲的特性，传统的直接截流断路方法不仅会产生大电弧影响关断损耗，还会在断路瞬间产生高峰值的过电压脉冲．针对直接截流方法的缺点，本文提出了一种基于混合脉冲变压器（HPPT）工作模式的新型开关断路方法，该方法采用电流过零瞬时断路方式换流．经过理论分析和仿真，验证了该方法的正确性与可行性，对同类开关断路技术的研究提供了十分重要的参考依据．
In the superconducting magnet energy storage pulsed power system, the key component of circuit is the opening switch, its opening performance directly determines characteristics of the output pulse. The traditional method of direct interruption not only produces large arc, but also transiently produces the high peak of over-voltage pulse. Based on the shortcoming of direct interruption and the working pattern of the hybrid pulse power transform- er(HPPT), the paper puts forward a new opening method which uses the zero-current conversion. Through theoretical analysis and simulation, the correctness and feasibility have been verified and it provides some important references for the study on the congener switching opening technology.
