摘　　要：电磁瞬态过程是大容量电力电子系统设计与分析的关键所在。该文从电磁能量变换、瞬态换流回路及系统可靠性的角度提出大容量电力电子变换系统电磁瞬态分析与控制技术;分析大功率器件瞬态建模与应用特性、杂散参数的提取及影响、不同时间尺度的电磁脉冲过渡过程、系统瞬态能量平衡关系等问题;分析器件与装置、集中参数与分布参数、控制与主回路之间的定量关系;阐述系统安全工作区、瞬态换流拓扑、主电路脉冲调制、能量平衡控制等分析和控制方法。应用结果表明:采用所提出的分析与控制技术进行设计可以显著提升大容量电力电子装置的性能及可靠性。The electromagnetic transient process is the key point in the design and analysis of high power converters. From the views of electromagnetic energy conversion, transient commutation loop, and system reliability, this paper proposed a series of analysis and control techniques for electromagnetic transient processes in high power electronic conversion systems. The following sub-topics were discussed： transient process modeling and application characteristics of high power devices, extractions and influences of stray parameters, electromagnetic pulse transient processes, and transient energy balancing relations. Quantitative relations were set up between device and equipment, lumped parameters and distributed parameters, control and main circuit, respectively. This paper also described analysis and control methods such as systematic safe operation area, transient circuit topology, power pulse modulation, and energy-balance control. Application examples indicate that the proposed techniques can significantly improve the performances and reliability of high power electronic equipment.
