中文摘要

狄克逊(Dickson)型DC-DC变换器因其优异的开关电压利用率受到广泛关注。混合开关电容(HSC)结构在提升无源元件利用率的同时,有效规避了慢速开关限制(SSL)。本文重点研究了HSC变换器的大信号电压纹波行为及其对无源元件利用率的影响,为高功率密度变换器的优化设计提供了理论支撑。

English Abstract

Dickson-type dc–dc converters have gained renewed interest in recent years due to their best-in-class volt-amp switch utilization. In addition, “hybrid” switched-capacitor (HSC) structures increase passive component utilization while avoiding the slow-switching limit (SSL), and yet, most HSC work to date has done little to assess large signal voltage ripple behavior and subsequent passive utilizat...
