摘　　要：电路仿真已经成为电力电子系统分析设计的基础性和支撑性技术之一,基于此形成的电力电子仿真软件是相关科学研究、产品开发和工程应用不可或缺的数值实验平台。然而,由于电力电子系统具有连续与离散过程相互混杂的特点,系统动力学行为跨越s到ns等多个时间尺度,其仿真技术和仿真软件发展仍面临诸多挑战和瓶颈问题。近期,相关系列研究提出了离散状态事件驱动(discretestate event-driven,DSED)的建模仿真理论方法,基于此形成了通用电力电子仿真软件,为解决电力电子混杂系统多时间尺度高效仿真提供了新的技术路线和解决方案。这一方法正在动态发展之中,为了更好地总结和展望其相关研究成果,文中首先分析电力电子系统的多时间尺度混杂特性,在此基础上阐述电力电子仿真技术的发展现状及面临的瓶颈问题,然后系统性地总结针对瓶颈问题提出的离散状态事件驱动建模仿真理论方法,进一步介绍和对比分析电力电子领域常用的商业仿真软件及基于离散状态事件驱动形成的DSIM仿真软件,最后展望相关电力电子仿真技术和仿真软件的未来发展方向。Simulation technology has become a fundamental technology in power electronics analysis and design. The corresponding simulation software has served as the indispensable numerical experiment platform for scientific research, product development and engineering application.However, due to the coexistence of the hybrid continuous and discrete process, the dynamics of the power electronics systems vary across multiple timescales(e.g. from seconds to nanoseconds), and the development of the power electronics simulation technology and software is facing significant challenges and bottlenecks. Recently, a series of related researches proposed the discrete state event-driven(DSED)modeling and simulation approach, and general-purpose power electronics simulation software was developed based on the DSED approach. The new approach and software provided a new technical route and solution for the effective simulation of multi-timescale power electronics hybrid systems. In its dynamic development, to better summarize this approach, the multi-timescale hybrid nature of power electronics systems was firstly analyzed in this paper, and the development and bottlenecks of power electronics simulation were discussed.Then, the DSED approach based on the concept of hybrid system was systematically introduced, and the development of power electronics simulation software was also described.Finally, the prospects of the DSED-based simulation technology and software were provided.
