工程实践背景下的荧光灯电路实验

Circuit Experiment of Fluorescent Lamp Under the Background of Engineering Practice

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,针对常规实验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,掌握周期性非正弦信号的分析方法。

In order to overcome?shortcomings in?general experiment of fluorescent lamp circuit,such as only reproducing the working?principle of fluorescent lamp,and methods how to improve power factor and lack in deep?exploration 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 electronic?ballast,wave distortion of power supply and danger caused by uncontrolled harmonic wave,students were led to know the problem of harmonic wave in power supply,master the analysis methods of non-sinusoidal signal.
