电力电子课程涉及四大变换及其控制,分别为AC/DC、AC/AC、DC/AC、DC/DC,课程的教学均围绕这几个知识点逐一展开。但相关技术的背景、应用对象比较模糊,电路原理的阐述比较抽象,学生缺乏学习的兴趣与动力。根据中频感应加热技术的原理及其装备的运行情况,尝试实施无源逆变技术的案例教学。让学生在学习课程的同时,获得该知识点的原理、背景与应用,获得除知识点之外的现实装备的概貌与运行情况,建立并加深对该知识点的理解与掌握,逐步建立自身的兴趣点与发展方向。教学实践表明,这种教学方法其效果明显,师生互动踊跃,学生反映良好。
The power electronics curriculum involves four major changes and their control, namely AC / DC, AC / AC, DC / AC, DC / DC, the teaching of the course revolves around each of these knowledge points one by one. However, in the background of related technologies, the objects of application are rather vague, the explanation of circuit principle is rather abstract, and the students lack the interest and motivation of learning. According to the principle of intermediate frequency induction heating technology and the operation of its equipment, try to implement case teaching of passive inverter technology. Let students acquire the principle, background and application of this knowledge point while learning the course, acquire the appearance and operation of the actual equipment except the knowledge point, establish and deepen the understanding and mastery of this knowledge point, and gradually establish their own Points of interest and direction of development. Teaching practice shows that this teaching method has obvious effect, active interaction between teachers and students, students reflect well.
