中文摘要

本文提出了一种新型单相单级Buck-Boost逆变器。该拓扑支持宽范围输入直流电压下的升降压运行,具备双向功率流和无功补偿能力,且仅需单个电感。通过将输出中性点连接至特定节点,有效消除了共模漏电流,提升了系统性能。

English Abstract

This paper presents novel single-phase single-stage buck–boost inverters. The proposed inverters provide buck–boost operation for a wide variation of the input dc voltage. In addition, the proposed inverters are bidirectional and provide reactive power. Further, they require only one inductor. The proposed inverters also eliminate the common-mode leakage current by connecting the output neutral to...
