The high-efficiency mode of electromagnetic launcher (EML) operation is investigated. The high-efficiency mode for some launchers is achieved when the EML is operated in zero exit current (ZC) mode. Several power supply strategies to achieve high-efficiency ZC mode are presented. The investigation defines the ideal high-efficiency power supply for high-efficiency ZC mode launcher operation. The ideal power supply, in conjunction with a well-designed EML, will approximate an ideal launcher. The principles presented apply to all noninduction EMLs even though the discussion is limited to conventional railguns and helical launchers and augmented railguns and high-efficiency helical launchers. Theoretical predictions are in good agreement with experimental measurements.

电磁发射器运行的高效模式

研究了电磁发射器（EML）运行的高效模式。当 EML 在零出口电流 (ZC) 模式下运行时，一些发射器的高效模式就实现了。提出了几种实现高效 ZC 模式的电源策略。该调查为高效 ZC 模式发射器操作定义了理想的高效电源。理想的电源与精心设计的 EML 相结合，将近似于理想的发射器。尽管讨论仅限于常规轨道炮和螺旋发射器以及增强轨道炮和高效螺旋发射器，但所提出的原则适用于所有非感应 EML。理论预测与实验测量非常吻合。
