从线圈到系统：WPT项目驱动与AI赋能的电路分析课程改革

From Coils to Systems: Project-Driven and AI-Enabled Circuit Analysis Course Reform for WPT

摘要: 针对电路分析基础课程教学中存在的知识点孤立、工程主线缺失、个性化指导不足等问题，本文提出以无线功率传输(WPT)系统为主线重构课程内容，打破传统章节线性次序，围绕“线圈建模–谐振分析–功率传输–等效变换–暂态保护”五个功能模块，设计五项递进式仿真任务，覆盖电路模型、等效变换、正弦稳态、谐振、互感、一阶暂态等核心知识点，并引入AI辅助教学。在测控工程专业78人的试点班中，期末卷面平均分提高6.7分，综合设计优秀率提升19%，学生对“电路理论理解更深入”的认同率从68%升至92%。实践表明，该模式显著提升了学生对知识体系的整体把握和工程实践能力。

Abstract: Aiming at the problems in the teaching of Fundamentals of Circuit Analysis, such as isolated knowledge points, lack of engineering mainline and insufficient personalized guidance, this paper proposes reconstructing the curriculum content with the wireless power transfer (WPT) system as the main thread. Breaking the linear order of traditional chapters, five progressive simulation tasks are designed around five functional modules: coil modeling, resonance analysis, power transfer, equivalent transformation and transient protection. These tasks cover core knowledge points including circuit models, equivalent transformation, sinusoidal steady state, resonance, mutual inductance and first-order transients, with AI-assisted teaching introduced. In a pilot class of 78 students majoring in measurement and control engineering, the average score of the final written examination increased by 6.7 points, the excellent rate of comprehensive design rose by 19%, and students’ recognition rate of “deeper understanding of circuit theory” increased from 68% to 92%. Practice shows that this mode significantly improves students’ overall mastery of the knowledge system and engineering practice ability.
