The Application of Project Driven Teaching Method in the Teaching of“Power Electronics”——Taking“Electric-Field Wireless Transfer”as an Example

目的:面向新工科背景下的育人要求,引入电场式无线输电项目,探究项目驱动教学法在《电力电子技术》教学课堂的应用。方法:教师讲解电场式无线输电项目传输原理后,将电场式无线输电项目中前级电路和后级电路拆解为逆变电路和整流电路,学生结合《电力电子技术》课堂内容自主搭建电路并进行仿真,在完成逆变电路和整流电路搭建后,教师指导学生尝试搭建电场式无线输电结构电路,得出传输结果。结果:全体学生均完成逆变电路和整流电路的搭建,其中70%左右的学生完成了电场式无线输电结构的搭建和仿真。结论:从学生的课堂表现和课后作业完成情况看,项目驱动教学法极大地提高了学生的学习兴趣,学生主动参与项目,不仅增强了学生的动手能力,还提高了学生的创新能力。

Objective:To meet the educational requirements of the“Emerging Engineering Education”background,introduce the electric field wireless transmission project and explore the application of project driven teaching method in the teaching classroom of“Power Electronics”.Methods:After explaining the transmission principle of electric field type wireless transmission project,the teacher disassembled the front and rear circuits of the electric field type wireless transmission project into inverter and rectifier circuits.Students independently built circuits and simulated them based on the content of the“Power Electronics”class.After completing the inverter and rectifier circuit construction,the teacher guided students to try to build electric field type wireless transmission structural circuits and obtain transmission results.Results:All students completed the construction of inverter and rectifier circuits,with about 70%of them completing the construction and simulation of electric field type wireless transmission structures.Conclusion:From the perspective of students'classroom performance and homework,project-driven teaching method greatly enhances students'learning interest.Students actively participate in projects,not only enhancing their hands-on ability,but also improving their innovation ability.
