摘要

摘要: 由于LCLC諧振變換器能夠同時實現(xiàn)開關管的零電壓、零電流開通和關斷，因此廣泛應用于行波管電源中。然而，在實際電路測試中出現(xiàn)的反向諧振電流以及開關管關斷時諧振電流不為零的問題，造成LCLC諧振變換器的效率下降。該文從LCLC諧振變換器的工作原理出發(fā)，推導了上述兩個問題出現(xiàn)的原因，并給出了解決方案。通過軟件仿真的方法，給出了用于LCLC諧振變換器的經(jīng)驗數(shù)值。最后，通過軟件仿真以及實際測試兩種方法驗證了上述分析。

Abstract: As the advantages of zero-current-switching and zero-voltage-switching, the LCLC resonant converters are widely used in power supplies of Travelling-Wave Tubes (TWT). However, the problems such as the reverse resonant current and the non-zero resonant current in the converter drop the efficiency. In this paper, the above problems are explained by the working principle of the converter and the solutions to the problems are also given. Based on the simulations, empirical data is given to guide the design of the LCLC resonant converters. Finally, the analysis is validated by the simulations and experiments.
