中文摘要

本文提出了一种单相转三相功率转换系统,采用并联整流器与串联逆变器结构,有效解决了单相到三相转换中的不对称问题。该拓扑结构不仅降低了整流电路处理的输入电流,还减少了逆变电路的输出电压应力,提升了系统整体的转换效率与性能。

English Abstract

This paper presents a single-phase to three-phase power conversion system with parallel rectifier and series inverter to cope with single-phase to three-phase asymmetry. Such converter guarantees both reduction in the input current processed by rectifier circuit and reduction of the output voltage processed by the inverter circuit. It is worth mentioning that, in spite of proposing a topology with...

该拓扑主要针对单相输入转三相输出的特殊应用场景,虽然阳光电源目前的主流产品(如组串式逆变器、PowerTitan储能系统)多为三相输入/输出,但该技术在户用光伏及小型工商业微网领域具有潜在参考价值。特别是其通过并联整流和串联逆变降低器件应力的设计思路,可为阳光电源研发高功率密度、低成本的单相转三相微型逆变器或小型储能PCS提供拓扑优化思路,有助于提升在复杂电网环境下的电能质量控制能力。
