电力电子混杂系统多时间尺度分析控制与应用(一):理论部分

Multi-timescale Analysis and Control of Power Electronics Hybrid Systems(Part Ⅰ): Theory

文中对电力电子混杂系统多时间尺度分析控制与应用研究进行总结,分理论和应用上下两篇。上篇针对电力电子系统在实际应用中急需解决的提升变换能力和可靠性问题,对电力电子科学进行再认识,认为电力电子科学是一门基于功率半导体开关组合模式的电磁能量高效变换的科学。基于再认识框架,解析电力电子系统的多时间尺度混杂特征,进一步明确广义混杂系统的概念。针对广义混杂系统提出数值凸透镜分析解算方法,并予以论证。最后对该方法的发展进行展望。

This paper summarized the researches on the multi-timescale analysis and control of power electronics hybrid systems. It is divided into two parts: theory and applications. The theory part propose a reconsideration framework of power electronics science based on the urgent need of improving the capability and reliability of power electronics systems in real applications. It points out that power electronics is a science about how to implement controllable conversion of electromagnetic energy based on power semiconductor switching devices and their combinations. According to the reconsideration framework, the multi-timescale and hybrid nature of power electronics systems is analyzed and the concept of the generalized hybrid system(GHS) is further proposed. A numerical convex lens for solving GHSs is discussed, and finally the prospect of this theory is concluded.
