Multiport Converter With Independent Control of AC and DC Power Flows for Bipolar DC Distribution

语言:

中文摘要

本文提出了一种多端口AC-DC变换器拓扑,实现了两个直流端口与一个交流端口之间的双向功率传输。该拓扑通过解耦功率流,可作为极电压平衡机制,以适应双极性直流配电系统中的不平衡负载。该方案通过两个三相两电平电压源变换器实现双极性运行。

English Abstract

A multiport ac-dc converter topology is proposed that offers bidirectional power transfer capability between the two dc ports and the ac port. The decoupling of power flows can be exploited as a pole voltage balancing mechanism to accommodate unbalanced dc side loads in bipolar dc distribution systems. The proposed topology gains bipolar operation by using two three-phase two-level voltage-sourced...
