中文摘要：

针对电力电子课程课时短、概念多、知识面广、实践性强等特点，该文讨论了基于MatlabGUI与Simulink结合的电力电子虚拟仿真实验平台的构建。以直流.直流变流技术主界面为例，叙述了主界面的内容，原理分析界面的内容和功能，运行界面的基本特征，以及闭环仿真实例分析。电力电子教学可视化平台界面友好、操作简单，其应用有助于加深学生对基本理论、基本概念的理解，提高实验教学质量，推进实验教学改革。

英文摘要：

In view of the advantages of short class time,more concepts,wide knowledge scope and strong practice of the power electronic curriculum,the construction of power electronic virtual simulation platform based on Matlab GUI(graphical user interface)and Simulink is discussed.Taking the main interface of DC?DC converting technique as an example,contents of main interface,contents and functions of principle analysis interface,basic characteristics of running interface and closed?loop simulation instance are described.The interface of visualization platform for power electronic teaching is friendly and easy to operate.It is helpful to deepen students'understanding of basic concepts,improve the quality of experimental teaching.Its application can deepen students′comprehension to the basic theory and concept of their courses,improve the experimental teaching quality,and promote the experimental teaching reform.
