-
摘要: 综合论述了高重复频率脉冲功率技术所面临的主要技术障碍和工程问题。从实用的角度归纳了脉冲功率源设计时经常遇到的矛盾关系。结合目前的技术发展动态，探讨了未来这项技术的发展趋势和主要方向。目前，高重复频率脉冲功率系统的主要瓶颈是开关技术；主要技术障碍包括冷却、效率及可靠性；主要矛盾体现在系统的紧凑性与绝缘要求、上升时间与峰值功率、工作参数与可变范围及技术性能与制作成本等方面；未来发展趋势主要包括模块化、通用化和智能化。Abstract: In this final article of the review series, Repetition rate pulsed power technology and its applications, the technological problems and the design difficulties are summarized. The operation parameters of a pulsed power system are mostly limited by the switching elements. The technical barriers are mainly cooling, efficiency, and reliability related issues. In addition, the complicated trade-off relations encountered in the pulsed power development are briefly explained. Management of these relations are fundamental engineering challenges for most pulsed power systems. Finally, from the authors viewpoint, the future development trends of this technology are discussed. The repetitive pulsed power technology will expectedly develop toward modularization, generalization, and intellectualization.
