中文摘要

本文针对三相隔离式交直流矩阵变换器(3P-IMC)开关数量多及缺乏开路故障容错能力的问题,提出了一种通用的空间矢量PWM(SVPWM)模型,并设计了三种非对称SVPWM(ASVPWM)方案,实现了在正常及故障状态下的安全运行。

English Abstract

The three-phase isolated ac–dc matrix converter (3P-IMC) inherits all the merits of the conventional matrix converter. But it also suffers from a large number of bidirectional switches and cannot operate safely in an open-circuit fault condition. Hence, with a general space vector PWM (SVPWM) model presented in this article, three types of asymmetrical SVPWM (ASVPWM) schemes are first proposed for...

该研究提出的非对称SVPWM及故障容错控制策略,对于提升电力电子变换器的可靠性具有重要参考价值。虽然阳光电源目前的主流产品(如组串式逆变器、PowerTitan储能变流器)多采用传统的两电平或三电平拓扑,但矩阵变换器技术在特定高功率密度、高隔离要求的工业电源或未来新型储能接口中具有潜在应用价值。建议研发团队关注该文中的容错控制算法,将其转化为对现有逆变器及PCS产品在极端工况下的故障保护逻辑优化,以提升系统在复杂电网环境下的生存能力。
