| 中文摘要: |
| 为使学生更深刻理解荧光灯电路实验的基础性和可扩展性,针对常规荧光灯实验的内容和要求相对简单,仅限于复现荧光灯的工作原理及如何提高功率因数,缺少对实际工程问题的深入探索,设计了荧光灯电路综合研究实验。从电子镇流器产生谐波、供电电源波形畸变、不受控制的谐波存在危害等工程实际问题切入,引导学生认识供电系统谐波的问题,掌握周期性非正弦电压信号的分析方法。几年的教学实践结果表明,本实验的开设可以培养学生养成研究的习惯,激发学生深入探究理论知识与实际工程实践之间的差异、自主学习相关知识的兴趣。 |

| In order to overcomeSshortcomings inSgeneral experiment of fluorescent lamp circuit, such as relativelySsimple, only reproducing the workingSprinciple of fluorescent lamp, and methods how to improve power factor and lack in deepSexploration in practical engineering problems, a comprehensive research experiment on fluorescent lamp circuit was designed to encourage students to understand deeply the fundamentality and extendibility of experiment of fluorescent lamp circuit. Begin with harmonic generation of electronicSballast, waveSdistortion of powerSsupplySand danger caused by uncontrolled harmonic wave, students were led to know the problem of harmonic wave in power supply, masterSthe analysis methods of non-sinusoidal voltage signal. Experiment teaching in recent years proves that this comprehensive research experiment can arouseSinterestsSof students to explore difference between theoreticalSknowledge and engineering practice, Sto learning relatedSknowledge actively. |
