基于Psim的电力电子探究性实验教学研究

Research on Inquiry Experiment in Power Electronics Teaching Based on Psim

电力电子技术课程具有工程性强、原理理解困难的特点,在探究性实验中,实验参数的确定往往较为困难,特殊实验现象的解释和理解也比较复杂。该文分别以降压斩波电路和三相全控桥整流电路为对象,采用Psim仿真来再现实验现象,确定实验参数,探究实验和理论上的难点问题。实践表明,在电力电子探究性实验中引入Psim仿真能够有效激发学生的学习兴趣,可以提高学生应用所学知识进行工程实践的能力以及实际的教学效果。

The power electronics technologT course has the characteristics of strong engineering and difficul）y in understanding the principle. In the inquiU experiments, the determination of the experimental parameters is often difficult, and the explanation and un- derstanding of the special experimental phenomena are more complex. In this paper, the Psim simulation is used to reproduce the ex- perimental phenomena, to determine the experimental parameters, to explore the experiment and to solve the difficult problems in the- oU. The practice shows that the introduction of Psim simulation in the inquiU experiment of power electronics effectively may stimulate the students＇ interest in learning the course, and improve the students＇ abili）y to apply the knowledge in the can effectively stimulate the students＇ interest in learning, and can improve the students＇ abili）y to apply the knowledge to the engineering practice and actual teaching effect.
