中文摘要

混合及谐振开关电容(SC)变换器通过有效利用有源和无源元件,有望实现比传统SC及磁性变换器更高的效率和功率密度。通过引入电感,设计空间获得了更多自由度。本文旨在深入探讨电容与电感在混合谐振SC变换器中的体积权衡关系,为高功率密度变换器的设计提供理论指导。

English Abstract

Hybrid and resonant switched-capacitor (SC) convertersenable efficient utilization of both active and passive components, and have the potential to achieve higher efficiency and higher power density than conventional SC and magnetic-based converters. One or more added inductors offer an additional degree of freedom in the design space. It is of great interest to understand the tradeoffsbetween cap...
