多模块互联电力电子系统稳定性和动态特性研究进展

由多个具有独立和完整功能的电力电子变流器通过相互级联和并联的方法连接起来，已经成为构成现代各种先进的复杂电力电子系统的基本形式。现有的电力电子技术体系大都是讨论单个变流器与简单特性的电源或负载之间的相互作用并进行相应的分析和设计的，对多模块（变流器）互联而成的电力电子系统中变流器之间的相互作用（包括级联时电源变流器和负载变流器之间的相互作用、并联变流器之间的相互作用等）以及由这种相互作用表现出来的整个电力电子系统的特性，亟待进行深入的认识和研究。本文将概述在多模块互联电力电子系统的稳定性和动态特性领域国际上近年来的发展历史和现状，并汇报总结作者所在的课题组近年来在该领域所取得的成果。
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.
