摘　　要：关于高校本科电气自动化专业电力电子技术课程实验教学使用的电力电子教学实验箱,在实验过程中频繁出现实验无法验证预期结果的情况,经反复测试发现,是因电力电子实验设备存在某些问题和缺陷而导致的。针对存在的问题和缺陷,实验室教学团队对晶闸管电路学习机进行了某些改进和改良,使得教学实验基本得以正常进行,同时对于无法改善的问题也作出了具体的原因分析。With regard to the experimental instrument box used in the experimental teaching of electrical & electronic technology course for the undergraduate electrical automation major in our university, there are frequent cases that the experiment can not verify the expected results. After repeated tests, we find that it is caused by some problems and defects in power electronic experimental equipment. In view of the existing problems and defects, the laboratory teaching team made some improvements to the learning machine of the thyristor circuit, so that the teaching experiment can be proceeded normally. At the same time, it also makes a specific analysis of the reasons for the problems that can not be improved.
