由多個具有獨立和完整功能的電力電子變流器通過相互級聯(lián)和并聯(lián)的方法連接起來，已經(jīng)成為構成現(xiàn)代各種先進的復雜電力電子系統(tǒng)的基本形式。現(xiàn)有的電力電子技術體系大都是討論單個變流器與簡單特性的電源或負載之間的相互作用并進行相應的分析和設計的，對多模塊（變流器）互聯(lián)而成的電力電子系統(tǒng)中變流器之間的相互作用（包括級聯(lián)時電源變流器和負載變流器之間的相互作用、并聯(lián)變流器之間的相互作用等）以及由這種相互作用表現(xiàn)出來的整個電力電子系統(tǒng)的特性，亟待進行深入的認識和研究。本文將概述在多模塊互聯(lián)電力電子系統(tǒng)的穩(wěn)定性和動態(tài)特性領域國際上近年來的發(fā)展歷史和現(xiàn)狀，并匯報總結(jié)作者所在的課題組近年來在該領域所取得的成果。
Abstract: Cascading and/or paralleling multiple power converters have become a common method to constitute all kinds of advanced power electronics systems. Current techniques and knowledge system of power electronics is mainly addressing interactions between a power converter and an ideal power source or load. There is a tremendous need to
understand and investigate interactions among power converters in a multi-module power electronics system, including the
interactions between source converters and load converters in cascaded connection, and the interactions among paralleled
power converters. The need is solidly extended to explore the system level performance of multi-module power electronics
systems. This paper reviews and summarizes research advances in this area around the world as well as reports recent progresses made by the authors’ research team.
