中文摘要

本文提出了一种基于耦合电感的单相共地非隔离逆变器,实现了单级电压升压与降压功能。该拓扑的共地特性有效消除了源端与负载间的漏电流,从而降低了电流与电压谐波,并改善了电磁兼容性。

English Abstract

This article presents a single-phase common-ground coupled inductor-based nonisolated inverter with a voltage boost in a single stage. The proposed inverter can also do buck (step-down) operation. The common ground nature of the proposed inverter eliminates leakage current flow between the source and the load. Leakage current flow in converters increases current and voltage harmonics, electromagne...
