说明：  对流层大气波导，可以使电波在较小的衰减下实现超视距传播，从而对无线电电子系统的运作产生严重的影响。对于通讯电路，它使系统间的相互干扰题目变得复杂；对于探测系统，产生的则是雷达空洞、超视距探测等题目。因此开展大气波导环境中电波传播特性及其应用的探究具有重大的理论意义和军事价值。 (Tropospheric waveguide, can make waves in the smaller attenuation achieve-the-horizon communication, and thus the operation of radio-electronic systems have a serious impact. For the communications circuits, which allows the mutual interference between systems has become a complex subject for the detection system is generated by the radar empty-the-horizon detection and other topics. Therefore, to carry out atmospheric environment of radio wave propagation characteristics of waveguides and its application to explore the theoretical significance and of great military value.)

最近 LCC 谐振变换器备受关注，因为它优于常规串联谐振变换器和并联谐振变换器：在负载和输入变化较大时，频率变化仍很小，且全负载范围内切换可实现零电压转换（ZVS）。本文介绍了LLC型谐振变换器的分析方法，回顾了LLC型谐振变换器的实际设计要素。其中包括设计变压器和选择元器件。采用一设计实例，逐步说明设计流程，有助于工程师更加轻松地设计LLC谐振器。(Recently LCC resonant converter has attracted much attention, because it is better than that of the conventional series resonant converter and parallel resonant converter in the load and input change, frequency change is still very small, and the whole range of the load switch can realize zero voltage switching (ZVS). In this paper, the analysis method of LLC resonant converter is introduced, and the practical design elements of LLC resonant converter are reviewed. Including the design of transformers and components. A design example is used to explain the design process step by step, which is helpful for engineers to design LLC resonators more easily.)
