摘要

本研究探讨了一种基于层叠阶梯结构的混合谐振开关电容(SC) dc-dc变换器的设计与实现。特别关注的是通过使用耦合磁性和合并的LC谐振结构来提高效率和功率密度，从而减小整体尺寸和功率损耗。采用耦合电感和集成LC谐振器实现了两相交错3对1变换器，效率为97.1%，输出功率高达180 W左右。研究了谐振槽的结构以及损失建模、耦合效应和设计策略。

Two-Phase Interleaved Resonant Switched-Capacitor DC-DC Converter with Coupled Inductors and Custom LC Resonator

This work explores the design and implementation of a hybrid-resonant switched-capacitor (SC) dc-dc converter based on the stacked-ladder architecture. A particular focus is on improving eﬃciency and power-density through the use of coupled magnetics and a merged LC resonant structure that can reduce overall size and power loss. A two-phase interleaved 3-to-1 converter is implemented with 97.1% eﬃciency for both a coupled inductor and an integrated LC resonator with output power up to around 180 W. A study of resonant tank configurations is presented along with loss modeling, coupling effects, and design strategies.
