摘要
电力电子系统集成是电力电子技术与材料、机械、化学、信息等多学科边缘交叉渗透的综合性工程,可实现电力电子系统的高可靠性、高功率密度、高效、环境友好和低成本。从开关单元和元件单元、电力电子标准模块、系统3个层次论述了电力电子集成系统建模技术的内容及现状。模块级建模主要包括建立电气、开关、传热、热力学模型以及模块的集成建模分析。系统级建模的目的是为了研究系统静态、动态和暂态性能,给出集成系统结构优化原则。探讨了电力电子集成系统建模技术的研究趋势。
Power electronics system integration is a hybrid and complex work which involves several subjects such as material, mechanics, chemistry, informatics and so on. It can realize high power density, high efficiency, high reliability, harmony with environment and low cost for power electronics system. The modeling of power electronics integrated system is analyzed from three layers： switching and component cell layer, standardized power electronics module layer and system layer. The module - layer modeling includes establishing electrical, switching, thermal, thermodynamics and integrated model. The goal of the system - layer modeling is to study the steady, dynamic and transient functions and give the structure optimization strategies of the power electronics integrated system. The research orientation in the future is also discussed.
