电力电子磁技术教学探讨

磁性元件为电力电子电路的关键器件之一.它们在现有教材中的相关内容不仅少而且零散,与其地位不相称.由于电力电子电路的开关方式以及控制方式的多样性,使得电路中磁性元件的工作模式比较复杂,成了学习的难点.为此,笔者在教学中增加了磁基础知识回顾、磁芯损耗和线圈设计技术以及磁性元件设计方法等磁技术基础内容,并积极研究了采用图形法与电磁场有限元仿真软件等磁技术教学方法.教学实践证明补充的教学内容和采用的教学方法均取得了良好的教学效果.

Discussions on Teaching of Magnetics in Power Electronic Technology

Magnetic components are a key elements for power electronic circuits. However , the teaching arrangements in available textbooks of power electronic technology for the components are not only little but also fragmented. Moreover, the components are also difficult for teaching and learning because they are complex. So teaching supplements including basic magnetics, core loss, winding techniques and design methods are arranged. And teaching method in the course is also discussed. Teaching experiences verify the teaching supplements and the teaching method achieve excellent results.
