摘　　要：电气工程及其自动化专业的基础课程—电力电子技术,理论性和实践性较强、原理抽象、波形分析较多,目前的教学模型多存在着不可更改参数、过度依赖开发软件等问题,因此学生领会知识点较为吃力,教学效果不够好。针对上述情况,设计了基于Visual Basic的电力电子电路动态演示教学系统,由其生成的对应.exe文件可脱离运行环境直接演示,其中包括整流、逆变、直流斩波和交交变流四种电力变换电路,模型完善且均可自主设定触发角、负载电阻等多项实验参数,并可以“同步”演示电路中信号流动路径与波形更新过程,直观、便捷,可极大地增强教学内容的生动性,激发学生学习兴趣,改善课程教学效果。The basic course of electrical engineering and its automation specialty,Power Electronics Technology,has strong theoretical and practical aspects,abstract principles,and more waveform analysis,most of the current teaching models have problems such as unchangeable parameters and excessive dependence on developing software.Therefore,it is difficult for students to grasp knowledge points,and the teaching effect is not good enough.In view of the above,a dynamic demonstration teaching system for power electronic circuits based on Visual Basic is designed,the generated.exe file can be directly demonstrated without running environment,which includes four power conversion circuits:rectification,inverter,DC chopping,and alternating current.Multiple experimental parameters such as load resistance,and the "synchronous" observation of the signal flow path and waveform changes in the circuit,intuitive and convenient,can greatly enhance the vividness of teaching contents,stimulate students’ learning interests,and improve the teaching effect of the course.
