串并联逆变器组合系统综述

摘要/Abstract

摘要：

主要介绍了四种以逆变器为标准化模块的串并联组合系统,其优点是可以缩短开发周期、降低开发成本、提高系统可靠性等。对该系统而言,关键是如何实现模块间的功率均衡和分布式、冗余控制。本文在现有文献的基础上分析讨论并总结了四种串并联逆变器组合系统的控制策略和未来的发展趋势,指出IPOP逆变器系统不仅实现了功率均衡,并且实现了分布式和冗余控制,而对于另外三种逆变器系统的研究目前尚停留在功率均衡控制策略上,分布式和冗余控制有待进一步研究。

Abstract:

In this paper, four kinds of series-parallel power conversion systems are introduced, in which multiple standardized inverter modules are connected in series or parallel at the output and input sides. The advantages of such systems include shortening the design process, reducing the cost, improving system reliability and so on. For these systems, the control objective is to achieve power balance among the modules and realize distributed and redundant control. Based on the existing reference, the control methods as well as the developing trend of these four kinds of systems are analyzed, discussed and summarized in the paper. It is also pointed out that for the IPOP inverter system the objectives of power balance and redundant control have both been actualized. While, for the other three kinds of inverter systems, the research still remain on the measures of power balancing and distributed and redundant control needs further study.

Key words: Inverter, combined system, current sharing, voltage sharing, distributed, redundant
