Abstract

With the significant development in photovoltaic (PV) systems, focus has been placed on inexpensive, efficient, and innovative power converter solutions, leading to a high diversity within power converters and new system configurations for grid-connected PV (GCPV) systems. During the last decade, multilevel inverter (MLI) designs have gained popularity in GCPV applications. This article provides a wide-ranging investigation of the common MLI topology in contrast to other existing MLI topologies for PV applications. Furthermore, the various modulation techniques used in MLI switching are elucidated and contrasted. The modulation strategies are reviewed with particular regard to their comparative suitability for the modulation of MLIs for PV applications. This article also provides a comparative analysis of available MLI control techniques and controllers for GCPV applications in recent times.

摘要

随着光伏（PV）系统的显著发展，人们将重点放在了廉价、高效且创新的功率转换器解决方案上，这导致了功率转换器的高度多样性以及用于并网光伏（GCPV）系统的新系统配置。在过去十年中，多电平逆变器（MLI）设计在GCPV应用中颇受欢迎。本文对用于光伏应用的常见MLI拓扑结构与其他现有MLI拓扑结构进行了广泛研究。此外，还阐述并对比了MLI开关中使用的各种调制技术。对调制策略进行了综述，特别关注它们对光伏应用中MLI调制的相对适用性。本文还对近期用于GCPV应用的可用MLI控制技术和控制器进行了比较分析。
