一种“电力电子技术”研究型教学方法与实践

A Research-Oriented Teaching Method and the Education Practice of Power Electronic Technology

本文对“电力电子技术”课程提出一种研究型教学方法并进行了实践探索,即充分利用课堂教学时间,将理论教学与现场实践验证紧密结合。为实现该教学方法,还通过构建脚本实验装置,使学生可以快速产生电力电子器件驱动脉冲,理解数字控制、模拟信号采样、脉冲宽度调度等概念。在实践中加深对电力电子装置工作原理的认识,完成对电力电子装置的控制,从而解决课程理论学习和实验结合不够紧密的问题,进一步提高学习效果。

A research-oriented teaching method for Power Electronics course is proposed in this paper and practiced, which is to connect the theory teaching with the on-site practical verification closely by making full use of teaching time in class. In order to realize the method, script-based experimental equipment is built, which is helpful for students to obtain driving pulses of power electronic devices quickly, and then master the concepts of digital control, analog signal sampling, pulse width modulation and so on. With the help of practice, the knowledge about principles of power electronic devices is deepen and the control of them is accomplished. Furthermore, the issue about lack of close connection between curriculum theory and practice is realized, and the learning effect is enhanced.
