摘要
针对高校自动化专业电力电子技术专业课课堂教学中难教和难学的特点,将Matlab/Simulink仿真软件引入课堂教学中。具体做法就是教师首先对正弦脉冲宽度调制(SPWM)技术的基本原理进行详细讲解,然后通过Matlab对所讲解的理论知识进行验证,最后教师通过工程实例,将SPWM控制技术具体应用到三相逆变器中,使学生明白学以致用的道理。经过实践证明在课堂教学中引入计算机仿真软件一方面可以验证所学课堂知识;另一方面通过仿真软件将课堂所学知识与实际应用相结合,可以激发学生的学习兴趣以及提高课堂学习效率。
According to the hard to teach and learn in classroom teaching for power electronic technology of automation specialty,the paper introduces the simulation software of Matlab / Simulink into classroom teaching. The particular way is that the teacher firstly explains the basic principle of sine pulse width modulation（ SPWM） technology detail,and then the teacher verifies the theoretical knowledge by Matlab. Finally teacher applies the SPWM control technology into the three-phase inverter through the project example,and lets the students to apply their knowledge and understand the truth. It can be proved by practice that the teaching method can validate the knowledge in the classroom,on the other hand it can combine the knowledge of classroom with the practical application through the simulation software. So it can stimulate the students＇ interest in learning and improve the efficiency of classroom lectures.
