摘　　要：针对电力电子技术在应用型本科教学过程中存在教学内容与实际应用结合度低等问题,提出基于建模和仿真的辅助教学方法。以DC/AC逆变器的教学内容为例,利用Simulink构建应用模型,内嵌FFT算法进行仿真分析。通过对比方法,准确地展示变换器实际电路工作特性、寻求更优的控制策略。其过程能让学生加深变换器电路结构、变换方式、控制策略等理论知识的理解,同时能极大地激发了学生的学习兴趣。帮助学生更好地理解和掌握核心专业知识,解决教学过程中的理论与实践结合度低的问题,有效地提高课堂教学质量。In view of the low integration of teaching content and practical application of power electronic technology in the process of application-oriented undergraduate teaching,this paper proposes an auxiliary teaching method based on modeling and simulation.Taking the teaching content of DC/AC converter as an example,the application model is constructed by using Simulink,and the FFT algorithm is embedded for simulation analysis.Through the comparison method,the actual circuit operating characteristics of the converter are more accurately displayed and a better control strategy is sought.The process enables students to deepen their understanding of converter circuit structure,transformation mode,control strategy and other theoretical knowledge,and can greatly stimulate students′interest in learning.Thus,it can help students better understand and master the core professional knowledge,solve the phenomenon of low integration of theory and practice in the teaching process,and effectively improve the quality of classroom teaching.
