中文摘要

LLC谐振变换器因其高效率广泛应用于开关电源领域。由于其多谐振特性和变结构行为，其通用时域解法极其复杂。本文提出了一种基于状态空间表示的直接时域分析方法，旨在克服现有分析方法的局限性，为LLC变换器的精确设计提供理论支撑。

English Abstract

The LLC resonant converter has been widely used in switched power supply covering several kinds of applications. Although it has been the focus of numerous analysis, their general time-domain (TD) solution is not completely enclosed due to its complexity given by the multiple resonance nature and its variable structure behavior. Consequently, the LLC converter design is also impaired by the lack o...
