中文摘要

本文提出了一种新型多端口逆变器拓扑,旨在通过单级功率变换将两个独立的直流源连接至三相负载。该拓扑专为光伏(PV)、燃料电池(FC)及电池储能系统(BESS)等混合可再生能源应用而设计,相比传统混合双级架构,具有更高的集成度和转换效率。

English Abstract

This article presents a novel inverter topology with a multi-port structure, which aims to connect two independent dc sources to a three-phase load by using single-stage power conversion. The proposed inverter has been developed to be used in hybrid renewable energy applications such as photovoltaic (PV), fuel cell (FC), and battery energy storage systems. Compared to the conventional hybrid dual-...
