电力电子电路探索性实验研究与实现

摘要

围绕高等院校开设创新类实验中的关键问题,研讨了探索性实验内容的设计方法,并以电力电子电路探索性实验为例说明方法的应用.针对本科教学实验受限于设备数量、场地面积等,提出了集约式探索性实验平台的构建方案.并设计了“广对象、宽理论”的实验内容框架以提高学生的实验自由度,打破以往实验教学中研究对象和方向单一的局限性.为了提高沟通效率、控制实验时长,提出了一种空间二维实验主题实施模式,并以三相全桥逆变电路故障诊断来说明设计原理.其设计思路是将所研究的问题分解在3个平面上,并在每个平面上具体指出研究对象和方式,直观呈现问题、模型、方法等基本脉络.最后建立科学的考核体系,从理论和实践难度两个角度独立分析,客观评价学生在实验过程中的各种能力.%This paper analyzes the key problem of the innovation type experiment in universities,proposes a new method of experiment content design.Power electronic circuit exploratory experiment is used as an example to illustrate the application of the method.Firstly,in view of the constraints of the hardware and area,intensive construction scheme of exploratory experiment platform is presented.Secondly,a new " wide objects,wide theory" experiment content framework is designed to break the limitations of previous single research objects and direction.Moreover,a twodimensional space experiment topic implementation mode is proposed.Its concept is to research the problem of decomposition in three planes,and show the specific objects on each plane,so that people can see problems,models,methods easily.A framework is given from theory and practice to realize students' assessment of science evaluation.
