摘要：本文提出了一種適合于特種雙向脈沖電源的軟開關電路，對該軟開關電路的拓撲結構和工作過程進行了較詳細的分析，并對軟開關電路與硬開關電路的損耗進行了分析和比較，對提出的軟開關電路進行了仿真分析。仿真結果表明，該軟開關電路能實現零電壓開通和關斷，輸出脈沖為雙向脈沖，有效減小了主開關器件的開關損耗，提高了電路的工作效率，表明了該軟開關電路應用于特種雙向脈沖電源的可行性。 敘詞：軟開關；損耗；雙向脈沖電源；零電壓 Abstract：A soft-switch circuit to special bidirectional pulse power is put forwarded in this paper，the topological structure and working process of this soft-switch circuit is analyzed in detail，the loss of circuit is analyzed and compared between the soft-switch and the hard-switch，and the soft-switch circuit is simulated. The results of simulation show that the soft-switch circuit can turn on or switch off in zero voltage，output bidirectional pulse，reduce the loss of the main switch effectively，enhance the working efficiency of circuit. At the same time, it shows that the soft-switch circuit is feasible in special bidirectional pulse power. Keyword：Soft-switch；Loss；Bidirectional Pulse Power；Zero Voltage；
