中文摘要

本文提出了一种新型控制技术,旨在实现直流-直流多相堆叠交错变换器的输出电流和电压无纹波。传统多相交错变换器的纹波消除仅依赖于相数且受占空比限制,而该技术克服了这一局限,显著提升了高功率变换系统的性能。

English Abstract

A novel control technique that guarantees a ripple-free output current and voltage of a dc–dc multiphase staked interleaved converter is proposed. The conventional multiphase interleaved converters have been extensively used in various applications. However, ripple cancellation in these converters solely depends on the number of phases and can only be achieved at specific duty cycles. On the other...
